Along with first responders, hospital personnel are called upon to provide immediate assistance in a radiation exposure emergency. Since this emergency is a low probability event yet still possible, training needs to be effective and leave a lasting impression.
A paper and pencil drill has a low expectation of being recalled in a high pressure situation. Reaching for the same radiation equipment that was used to train with ensures better care, more efficiently and with the highest degree of effectiveness. Providing personnel the ability to manipulate controls on radiation detection equipment without exposing them drives the effect practical training home.
