Question

The maximum permissible surface exposure rate per hour for a radioactive label White I is:

a) 0.5 mR/hr.
b) 10 mR/hr
c) 100 mR/hr
d) 1000 mR/hr

Answer 1

The maximum permissible surface exposure rate for a White I radioactive label is 0.5 mR/hr, a safety measure to minimize radiation exposure risks.

So, the correct answer is a) 0.5 mR/hr.

Step-by-step explanation:

The maximum permissible surface exposure rate per hour for a radioactive label White I is 0.5 mR/hr. This limit is a safety guideline to protect individuals from the harmful effects of exposure to ionizing radiation. It is critical to adhere to these limits to minimize the risks of radiation damage, such as radiation-induced cancer or genetic defects.

For example, in the provided bar graph about Radiation Doses and Regulatory Limits, the annual public dose limit set by the Nuclear Regulatory Commission (NRC) is shown as 100 mrem, or 0.1 rem, which emphasizes the tight regulation around radiation exposure to ensure public safety.

So, the correct answer is a) 0.5 mR/hr.
