A supervisor spends a day inspecting a nuclear plant for potential radiation leaks. She has to move throughout the plant inspecting all the equipment and machinery. She needs to take two different radiation detection devices to help ensure her safety and to find radiation leaks. She needs the results immediately. Which two devices would be the best choices for the task?

A Geiger counter is portable and gives immediate readings, so the supervisor can check equipment as she moves through the plant. A scintillation counter also provides rapid, sensitive detection of radiation and can help locate leaks. A film badge requires later processing, while a cloud chamber is not a practical portable choice for inspecting the whole plant.
