A new Electronic Neutron Dosimeter (END) forreliable personal dosimetry

摘要

Tests of existing electronic neutron dosimeters by military and civilian groups have revealed significant performancelimitations. To meet the operational requirements of emergency response personnel to a radiological/nuclear incident aswell as those in the nuclear industry, a new END has been developed. It is patterned after a unique commercial neutronspectral dosemeter known as the N-probe.It uses a pair of small special scintillators on tiny photomultiplier tubes.Special electronics were designed to minimize power consumption to allow for weeks of operation on a single charge.The size, performance, and data analysis for the END have been designed to meet/exceed international standards forelectronic neutron dosimeters. Results obtained with the END prototype are presented.
