  5. 9. Neutron shielding material.
  6. 15. The energy deposited in a small volume of matter
  7. 17. The effects that occur by chance and which may occur without a threshold level of dose, whose probability is proportional to the dose and whose severity is independent of the dose.
  8. 19. The unit of exposure.
  9. 21. The inverse square law is a technique of external radiation protection.
  10. 22. The effect that occur with dose-dependent severity. These effects generally do not occur below a certain threshold value.
