Agent Detection - Radiological

The Geiger Mueller tube commonly known as the geiger counter records amount of radiation by counts per minute in an area per unit of time. It is used to perform surveys for external contamination such as gamma and beta however, alpha detection requires special probes.

More sophisticated devices exist today including counters with probes as well as smaller portable handheld units.

Dosimeters measure cumulative amount of radiation an individual receives such as the thermolluminescent dosimeter (TLD) or film badge which detects gamma and beta exposures in rems however, it requires processing to determine exposure levels. The pocket dosimeter, which detects gamma radiation, has the capability to be directly read when held up to a light source.
