Biological countermeasures in space radiation health.
Exposure to the types of ionizing radiation encountered during space travel may cause a number of health-related problems, but the primary concern is related to the increased risk of cancer induction in astronauts. The major types of radiation considered to be of importance during space travel are protons and particles of high atomic number and high energy (HZE particles). It is now clear that ...
متن کاملBiological Effects of Space Radiation
The radiation exposure in space missions can be reduced by appropriate measures, but it cannot be prevented. The reason is that space radiations due to their high energy deeply penetrates in matter. In comparison to the shielding thickness of the atmosphere of approximately 10 meter water equivalent, a spacecraft provides only 1-30 cm shielding depending on the equipment installed inside the sp...
