Answer to Problem 55A
Film badge is used for monitoring exposure to ionizing radiation. People who work with ionizing or near ionizing radiation must be wearing the film badges
Explanation of Solution
People who work with ionizing or near ionizing radiation must be wearing film badges while they are at work to monitor their exposure to this radiation.
It is important to say that film badges do not protect people from radiation, only monitor the level of exposure.
The working of film badges is defined as follows: The film is removed and is developed at specific intervals and by comparing the darkness of this film in all the exposed areas, we can determine the strength and type of radiation exposure.
