a. Radiobiological effects resulting from the following environments shall be analysed for all manned missions:
1. trapped proton and electron belts (terrestrial and other planetary belts);
2. solar protons and ions;
3. cosmic ray protons and heavier nuclei;
4. bremsstrahlung produced as secondaries from electrons;
5. secondary protons, neutrons and other nuclear fragments which can be generated in atmospheric showers in the planetary environment or within the spacecraft or planetary-habitat structure, including the body itself.
NOTE This contribution is particularly important for cosmic-ray induced secondaries.
6. emmisions from radioactive or nuclear-energy sources on the spacecraft.
NOTE For example, RTGs generating g-ray and neutron radiation.
