1. Choose one exposure situation in our real life, which needs to be considered in the scope of radiological protection

2. Define

2-1) Source of exposure

2-2) Type of exposure situation

2-3) Category of exposure

2-4) Exposed individuals

2-5) For optimization of protection, which source-related restriction will be applied (dose constraint of reference level) and which band of constraint or reference level sill be chosen (<1, 1~20, >20mSv)

3. Provide the reason and support for your opinion

4. If the situation is already in the scope, it is necessary to provide details of the current system of radiation protection
