Section 5.1．Radiation protection
In daily life, most of the natural radiation cannot be avoided. However, when we are close to a radiative source, there are three simple ways to protect yourself from radiation:
1. Distance: Stay away from a radiation source as far as possible
2. Time: Minimize the time of exposure
3. Shielding: Use adequate shielding such as lead shield or lead-lined apron
If you visit a place involving the use of radiation, please follow the recommended safety procedures and do not enter unauthorized areas.
