This monitor, which consists of a Ge detector and a guard detector, can identify and quantify the nuclei by applying the anti-coincidence method in spite of considerable background. In order to determine the Germanium crystal size and optimize a dewar size of a Ge detector, the fundamental property data of cooling system is needed in the design. In the present study, a characteristic test for Ge detectors has been carried out to examine the property of cooling system, such as the duration for which the temperature of Germanium crystal reached below -150 degrees and LN2 consumption. From the obtained results, it was found that the Ge detector will be used for responding to radiation emergency accidents.}, pages = {128--130}, title = {Development of a Portable in vivo Monitor for Radiation Emergency Accidents}, volume = {A SPECIAL ISSUE}, year = {2005} }
