Abstract:
1. A radiation dosimetry system for determining tampering or correcting for environmental conditions, said radiation dosimetry system comprising: a detector system having at least two radiation detectors, a first of said at least two radiation detectors being made of optically stimulated luminescent (OSL) material and a second of said at least two radiation detectors being made of a thermoluminescent (TL) material, said first radiation detector outputting a first detection signal in response to a radiation impacting said detector system, said second radiation detector outputting a second detection signal in response to the radiation impacting said detector system; an analysis system receiving and analyzing said detection signals to determine a dose or dose rate of the radiation for each of said first radiation detector and said second radiation detector, said analysis system comparing said dose or dose rate of said first radiation detector to said dose or dose rate of said second radiation detector to determine whether said dose or dose rate of said first radiation detector differs from said dose or dose rate of said second radiation detector thereby indicating tampering or permitting correction for environmental conditions.
