1. occur below a certain threshold value.
2. 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.
3. We can call gamma ray and x-ray ray in the other name.
4. The SI unit of equivalent dose.
