Optimisation. transmitted. absorbed. reflected. 1. transmission. Radiation passes through atmosphere unimpeded.. Shortwave and longwave “windows” . 2. absorption. Energy is transferred to absorber; absorber emits energy. Radiation effects:. Deterministic effects. Stochastic effects. Deterministic effects. A deterministic effects has a threshold in dose.. The severity of the effect is dose related.. Radiation induced cataracts are an example of a deterministic effects.. What type of radiation is most harmful It depends on whether your exposure to radiation is internal or external beta particles Radioactive materials thatRadiation can affect the bodyThese adverse hea Summary/Conclusions and Recommendations – Day 3. From RERF LSS: . Excess relative risk goes down with age of exposure.. Excess absolute risk goes up with age, as the baseline goes up.. Excess risk seem to linearly related to the dose of radiation . Radiation refers to the process that is concerned with the passage of energy between places through space. . It is the radiation generated by sun that . regulates the temperature of earth. . .

Radiation is the emission of energy in the form of waves or particles. Radiation that is so powerful that it can remove electrons from atoms is called ionizing.. Examples of types of ionizing radiation are x-rays from medical machines and gamma rays from radioactive substances. . Bálint Vecsei dr..
