Question

Which of the following statements regarding film badges is (are) correct?

1. Film badges should be read quarterly.

2. Film badges must not leave the workplace.

3. Film badges measure quantity and quality of radiation exposure.

Answer 1

Film badges measure the quantity and quality of radiation exposure, and although they are often kept at the workplace, the frequency of reading them can vary.

Step-by-step explanation:

Film badges are used to measure exposure to radioactivity and are important for anyone regularly dealing with radioactive materials. The badges contain film that gets fogged upon exposure to radiation; the degree of fogging indicates the amount of radiation exposure. Statements regarding film badges:

• Film badges should be read periodically, but not necessarily quarterly. Different policies may dictate more frequent readings.
• It is best practice for film badges to remain at the workplace to prevent personal radiation exposure from being confused with occupational exposure.
• Film badges do measure the quantity and quality of radiation exposure, as they contain film and absorbers that determine both the amount and penetrating ability of radiation.

Therefore, statement 3 is correct.
