Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

The integral gamma-ray counting efficiency was measured for six CdTe detectors using gammas from 57Co, 85Kr, 137Cs, and 60Co. Changes in efficiency were measured as a function of temperature (-50 to 66°C), detector bias (50 to 100 V), pulse clipping time (0.25 to 1.6 µSec), and energy threshold setting (25, 50, 75, and 100 keV). The change is mainly due to trapping and detrapping of charge carriers. For a clipping time of 1 µ sec, changes in efficiency tiS high as 300% were observed over the temperature range -50 to 66°C. This change in efficiency was reduced to <10% by using only the fast component of the pulses generated. Total gamma-ray efficiency approaching the theoretical limit was measured at 23°C. Presently, CdTe detectors are not intended for use as spectrometers, but are intended to be used as gamma-ray counters over a wide temperature range.
