A survey meter’s primary goal is to detect the presence of radioactive contamination in the form of alpha, beta, gamma, or neutron particles or x-rays. Typically, the devices are handheld, point-and-shoot, battery powered, and light for ease of use in potentially harsh environments. Meters measure the radiation in terms of a count or radiation dose. Counters are specific to one or two particles and indicate the presence of said particles with clicks or an alarm. First responders use the device to determine if an emergency resulted radioactive contamination. The devices allow the operator to determine the type of radiation and the amount so as to properly handle the situation.
