Problem 48Q
Describe the outcomes of radiation exposure at different doses (in rem).
Solution 48Q:
Here, we are going to describe the outcomes of radiation exposure at different doses.
Step1:
The main unit of radiation exposure is rem(roentgen equivalent man). It measures the amount of ionization in the air caused by radioactive decay of nuclei.
Step2:
Radiation exposure can be specified in terms of the radiation dose. The two important categories of dose are:
- Physical dose or absorbed dose
- Biological dose or dose equivalent
Low-dose radiations are not harmful but high-dose radiations may lead to death. Radiation doses above 300 rem can be fatal and doses above 600 rem are almost certain to be fatal.
