Resumen
The paper analyses one-dimensional simple waves and small-amplitude disturbances in radiating and scattering grey gas. The governing equation of radiation acoustics describing the dynamics of simple waves is derived. Radiation-thermal dissipation conditions and radiation resistance force are introduced into this equation to describe the propagation and attenuation of various radiation perturbation waves. To study non-equilibrium wave phenomena in a radiating medium, the phenomenological Whitham method is used. This method is an effective way to analyse fundamental modes when more than one velocity appears in the governing equation. The use of this method is demonstrated in the paper by considering the evolution of one-dimensional harmonic waves caused by a short-wave initial perturbation of the equilibrium state of the radiating and scattering medium. For all wave modes, analytical solutions have been obtained, which allow us to understand their physical significance. These solutions can be, in particular, an additional test for radiative hydrodynamic codes operating in the radiative acoustics regime. The general approach can be useful in the development of higher-order Godunov numerical schemes for radiation hydrodynamics problems.

Resumen
The paper analyzes one-dimensional simple waves and small-amplitude perturbations in radiating and scattering gray gas. The governing equation of radiation acoustics describing the dynamics of simple waves is derived. The conditions of radiation-thermal dissipation and radiation resistance force are introduced into this equation to describe the propagation with dissipation and attenuation of various radiation perturbation waves. The phenomenological approximate Whitham method is used to investigate non-equilibrium wave phenomena in radiative medium. This method is an effective way to analyze fundamental modes when more than one velocity appears in the governing equation. The use of this method is demonstrated in this paper by considering the evolution of one-dimensional harmonic waves caused by a short-wave initial perturbation of the equilibrium state of the radiating and scattering medium. Analytical solutions are obtained for all wave modes, which allow us to interpret their physical meaning. These solutions can be, in particular, an additional test for radiative hydrodynamic codes operating in the radiative acoustics regime. The presented approach may be useful in detailing higher-order numerical Godunov schemes for radiation acoustics problems.

Resumen
DNA repair eukaryotic cells have additional protective mechanisms that avoid uncontrolled interaction of different parts of the chromatin and damaged regions. Key factors here are the regulation of chromatin density and mobility. The 4D (temporal and spatial) organization of chromatin is controlling this security barrier by regulating the accessibility of genes, flexibility of DNA, and its ability to move inside the nucleus. How this regulation mechanisms are involved in DNA repair upon radiation damage is until now rarely known but an important part to understand the enhanced effectiveness of high linear energy transfer (LET) particles. The damage recognition via PARP1 and the subsequent chromatin decondensation via PARylation is a crucial step in the DNA damage response (DDR). Upon We used the SNAKE microbeam with a beam spot size of <1 µm to induce highly localized DNA damage in living cells using 55 MeV Carbon ions to investigate the chromatin rearrangements in the early stage of DDR. The nuclei were irradiated with a cross pattern consisting of 1000 ions per spot and 25 spots per cell either with one (11 000 Gy), two (22 000 Gy), or three crosses (33 000 Gy). The chromatin rearrangement was imaged live for several minutes after irradiation at the beam using SiR chromatin stain. Upon 91% of the cells show a localized decondensation starting from a few seconds up to minutes after irradiation. The chromatin is decondensed by 6%-8% in the beam path with a local condensation at the edges of up to 8%. Our results suggest that chromatin decondensation is a fast process in the first few seconds after damage induction. Furthermore, decondensation status does not change over minutes, which gives evidence that this process and therefore DDR is paused or even stopped. In combination with the existing knowledge about early reactions to damage induction our data support the model of PARP induced chromatin decondensation. Furthermore, it is evident that also ultra-high doses of radiation are, in first place not able to inactivate initial basal mechanisms as response to damage induction.

Resumen
In the X-ray spectral fluorescence analysis, the anisotropy of primary radiation results in an uneven radiation of a sample’s surface, strengthening the role of some sections and weakening the role of others. The goal of the current work was to determine the minimal distance from the window of the X-ray tube with a cone-shaped anode at which the intensity of the sample’s radiation becomes homogeneous. The research method was the computer modeling of the X-ray fluorescence experiment. The working model was built on the basis of two equations for the densities of the fluxes of braking and characteristic radiations of the massive anode, which took into account the absorption of primary radiation by the anode’s material and the back-scattering of electrons. The ring source was represented in the model as the sum of infinitely small linear elements of equal power, and the sample was disc-shaped and coaxial with the source. The calculation diagram was very well consistent with the experimental diagram of radiation’s direction described in the research literature. Two spatial distributions were calculated. The first one described the distribution of primary radiation’s intensity on the surface of the sample, while the second one described the distribution of the fluorescent radiation, which was more valuable for the X-ray spectrometry. The calculations showed that although the second distribution, unlike the first one, considered the absorption of the primary radiation and secondary radiation in the sample, the shapes of both radiations were close. It was demonstrated that the area of the sample, which carried the most information on the composition of the irradiated material, was ring-shaped, and the width of this ring depended on the distance to the X-ray tube’s window. As the distance increased, the diagram of the spatial distribution of the radiation’s intensity became smoother, and, when the distance exceeded two diameters of the anode, the radiation became homogeneous. The constructed model, which considered the anisotropy of the primary analysis, could be applied in the method of fundamental parameters of X-ray fluorescence analysis for a spectrometer with compressed geometry.

Resumen
A coupled radiation-structure analysis of turbulent, non-premixed, strongly radiating acetylene/air flames is described. The analysis extends the laminar flamelet concept to include the effects of local radiative heat loss/gain. A new method for the calculation of the radiative source term is presented. New measurements of mean and fluctuating emission temperatures and radiation intensities, and previous data concerning flame structure are used to evaluate the predictions. Results show good agreement between measurements and predictions of flame structure similar to past uncoupled calculations. The mean emission temperatures and the mean visible radiation intensities are substantially underpredicted by the uncoupled analysis. The coupled calculations provide reasonable estimates of both quantities.

Resumen
The paper deals with the problems of mathematical simulation of aircraft engine jet exhausts radiation, the simulation being carried out by means of shader subroutines for the concurrent computation of the radiative transfer equation on the video card resources. The combination of an analytical model of an isobaric jet and ray tracing of computation of the radiative transfer equation allows us to develop a flexible model of aircraft jet radiation, the model taking into account the main parameters of streams in the jet and in the co-current flow, the spectral lines of the radiating components, and provides real-time computation. For the graphic implementation of the model, the OpenGL standard is used

Resumen
Radiation is widespread in nature, including ultraviolet radiation from the sun, cosmic radiation and radiation emitted by natural radionuclides. Over the years, the increasing industrialization of human beings has brought about more radiation, such as enhanced UV-B radiation due to ground ozone decay, and the emission and contamination of nuclear waste due to the increasing nuclear power plants and radioactive material industry. With additional radiation reaching plants, both negative effects including damage to cell membranes, reduction of photosynthetic rate and premature aging and benefits such as growth promotion and stress resistance enhancement have been observed. ROS (Reactive oxygen species) are reactive oxidants in plant cells, including hydrogen peroxide (H2O2), superoxide anions (O2•−) and hydroxide anion radicals (·OH), which may stimulate the antioxidant system of plants and act as signaling molecules to regulate downstream reactions. A number of studies have observed the change of ROS in plant cells under radiation, and new technology such as RNA-seq has molecularly revealed the regulation of radiative biological effects by ROS. This review summarized recent progress on the role of ROS in plant response to radiations including UV, ion beam and plasma, and may help to reveal the mechanisms of plant responses to radiation.

Resumen
This study seeks to provide a novel approach for producing technologically viable new radiation shielding materials to meet the safety requirements for use in medical X-ray imaging facilities. The approach was based on dispersing micro-sized and nano-sized heavy element fillers into polymeric materials using different filler dispersion methods such as melt-mixing, ion implantation and electrospinning. These materials have high potential application for shielding of X-rays in diagnostic radiology purposes.

Resumen
Fifty percent of solid cancers are treated with radiation therapy (RT). The dose used in RT is adjusted to the most sensitive individuals so that not more than 5% of the patients will have severe adverse healthy tissue effects. As a consequence, the majority of the patients will receive a suboptimal dose, as they would have tolerated a higher total dose and received a better tumor control. Thus, if RT could be individualized based on radiation sensitivity (RS), more patients would be cured and the most severe adverse reactions could be avoided. At present the mechanisms behind RS are not known. The long term aim of this thesis was to develop diagnostic tools to assess the individual RS of breast cancer patients and to better understand the mechanisms behind the RS and radiation effects after low dose exposures. The approach was based on the hypothesis that biomarkers of individual RS, in terms of acute adverse skin reactions after breast cancer RT, can be found in whole blood that has been stressed by low doses of ionizing radiation (IR).  To reach this goal two different approaches to identify biomarkers of RS have been investigated. A protocol for the analysis of differential protein expression in response to low dose in vitro irradiated whole blood was developed (paper I). This protocol was then used to investigate the proteomic profile of radiation sensitive and normo-sensitive patients, using isotope-coded protein labeled proteomics (ICPL). The results from the ICPL study (paper III) show that the two patient groups have different protein expression profiles both at the basal level and after IR. In paper II the potential biomarker 8-oxo-dG was investigated in serum after IR. The relative levels of IR induced 8-oxo-dG from radiation sensitive patients differ significantly from normo-sensitive patients. This indicates that the sensitive patients differ in their cellular response to IR and that 8-oxo-dG is a potential biomarker for RS.

At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 3: Manuscript.

Resumen
An analytical approach for solving both transient and steady state conduction and surface radiation problems is presented. The method is based on the use of a Green’s function, and the temperature field is obtained by solving an integral equation. This is in contrast to the approach presented in radiative heat transfer texts in which temperature profiles are obtained from the simultaneous solution of coupled integral and differential equations. The analysis presented in this paper provides insight into the solution of this important class of problems. The method is illustrated by solving two representative problems. The first problem considered is the steady state analysis of radiating fins, which are frequently incorporated in the design of spacecraft. The second problem considered is the transient analysis of a radiating target, which is used to determine the temporal response of radiation thermometers.

Resumen
The advancement in technology has resulted into development of Telethrapy and X-ray machine which has high potential hazards of ionizing radiation to user and patient exposed. Ionizing radiations are referred as gamma rays photons. X-rays can cause conjunctivitis and sterility. Ionization radiation is hazard both in radiotherapy and nuclear medicine department. The energy of this radiation is around 10eV, higher the energy of radiation greater is hazard because of penetration into tissues the basic protection rule is either move way from source of radiation or put absorber in between. These equipments are tools of diagnostics, therefore international commission on radiological protection (ICRP) ha recommended that exposure to radiation be kept minimum. Designing of teletherapy facilities play important role in protection and monitoring of radiations. The author has analyzed the protective measures and monitoring of radiations in various hospitals in public and private sector in Rawalpindi / Islamabad Pakistan. It has been observed that only in military hospitals strict protective and monitoring measurers are taken against radiations but in other public and private sector hospitals such measure are compromised due to lack of proper awareness. Pakistan nuclear regulatory authority (PNRA) is taking measures for ensuring protective and monitoring measurer against radiations and arousing awareness to all concerns.

Resumen
The radiation from a target received by an infrared system is called apparent radiation. The apparent radiation includes three major factors: the ambient radiation reflected and transmitted by the target, the emissivity of the target, and the true temperature of the target. Due to lack of theory and method to measure the ambient radiation, it is impossible to quantitatively measure the self-radiation properties of the target. To solve this problem, we have presented a new concept called equivalent blackbody radiation1 and quantitative measurements have been done for an opaque greybody.

Resumen
The transported PDF method coupled with a detailed gas-phase chemistry, soot model and radiative transfer equation solver is applied to various turbulent jet flames with Reynolds numbers varying from ∼ 6700 to 15100. Two ethylene–air flames and four flames with a blend of methane–ethylene and enhanced oxygen concentration are simulated. A Lagrangian particle Monte Carlo method is used to solve the transported joint probability density function (PDF) equations, as it can accommodate the high dimensionality of the problem with relative ease. Detailed kinetics are used to accurately model the gas-phase chemistry coupled with a detailed soot model. Radiation is calculated using a particle-based photon Monte Carlo method, which is coupled with the PDF method and the soot model to accurately account for both emission and absorption turbulence–radiation interactions (TRI), using line-by-line databases for radiative properties of CO2 and H2O; soot radiative properties are also modeled as nongray. Turbulence–radiation interactions can have a strong effect on the net radiative heat loss from sooting flames. For a given temperature, species and soot distribution, TRI increases emission from the flames by 30–60%. Absorption also increases, but primarily due to the increase in emission. The net heat loss from the flame increases by 45–90% when accounting for TRI. This ixs much higher than the corresponding increase due to TRI in nonsooting flames. Absorption TRI was found to be negligible in the laboratory scale sooting flames with soot levels on the order of a few ppm, but may be important in larger industrial scale flames.

Resumen
There are several terms which describe the Planckian radiation temperature for light sources, including radiance temperature, colour temperature, correlated colour temperature, distribution temperature and ratio temperature. This document provides descriptions of these terms, information on their applicability, and highlights relationships between them so that they may be consistently applied in all applications. Definitions and additional explanatory information for each term are given in this document. Obviously, the greater the difference between the radiation considered and a Planckian radiator, the more tenuous the interpretation of the temperature attribution. Guidelines as to agreed reasonable limits of applicability, if any, are therefore also given, together with information on the calculation of the associated measurement uncertainties where relevant. Keywords: Planckian radiation, Planckian radiatior, Thermodynamic temperature, Planckian radiator temperature, Blackbody temperature, Radiance temperature, Colour temperature, Correlated colour temperature, CCT, Distribution temperature, Ratio temperature

Resumen
ESA's EarthCARE (Cloud, Aerosol and Radiation Explorer) mission - scheduled to be launched in 2024 - is the largest and most complex Earth Explorer to date and will advance our understanding of the role that clouds and aerosols play in reflecting incident solar radiation back into space and trapping infrared radiation emitted from Earth's surface. The mission is being implemented in cooperation with JAXA (Japan Aerospace Exploration Agency). It carries four scientific instruments. The Atmospheric Lidar (ATLID), operating at 355 nm wavelength and equipped with a high-spectral resolution and depolarisation receiver, measures profiles of aerosols and thin clouds. The Cloud Profiling Radar (CPR, contribution of JAXA), operates at 94 GHz to measure clouds and precipitation, as well as vertical motion through its Doppler functionality. The Multi-Spectral Imager provides across-track information of clouds and aerosols. The Broad-Band Radiometer (BBR) measures the outgoing reflected solar and emitted thermal radiation in order to derive broad-band radiative fluxes at the top of atmosphere. The Mission Requirement Document defines the scientific mission objectives and observational requirements of EarthCARE. The document has been written by the ESA-JAXA Joint Mission Advisory Group for EarthCARE.
