Charge Transport Tactical Dosimeter,
Abstract
The charge transport dosimeter, an instrument capable of measuring doses of gamma rays and fast neutrons delivered to personnel, is intended as a second generation Army tactical dosimeter, replacing the present IM185. The instrument's response to gamma rays is based on the tendency of high atomic number materials to reflect the energetic electrons produced within matter by gamma rays, causing a positive charge to collect on a thin central conductor surrounded by a low atomic number insulator. It is made sensitive to fast neutrons as well by surrounding the collector with a hydrogenous radiator. By proper selection of collector and radiator dimensions and compositions, its quantum energy response and neutron-to-gamma response ratio can be tailored to match a wide choice of desired characteristics. A number of experimental models of the charge transport dosimeter have been built and successfully tested on gamma rays and fast neutrons at various dose delivery rates. Results show that the instrument promises to satisfy all Army requirements for a tactical dosimeter while substantially reducing both production and maintenance costs.
