General Description
Tru-Dac is a personal Alarming Alph/Beta Monitor. Detects airborne radiation for inhalation dose in an ultra-portable package. The device can be used for either First Responders or Laboratory use. Utilizes a membrane filter. Collected airborne activity is analyzed by internal detector with Alpha spectroscopy and gross Beta counting.
Technical Description
Aerosol is collected at the surface of a filter. A semiconductor detector is used to Detect Alpha & Beta particles. Separation of long living Alpha Nuclides from Radon daughters by using alpha-spectroscopy. Beta gross counting and natural background subtraction is also included in the detection system.
