CONTAINER SECURITY DEVICES, SYSTEMS, AND METHODS

摘要

A dosimeter is disclosed for use in container including outer walls defining an interior volume, the dosimeter including: a radon detection element adapted to detect a radon level for the interior volume; a neutron detection element adapted to detect a neutron level for the interior volume. The dosimeter is adapted to measure the radon level and neutron level for a period of time, compare the measured radon level to a first threshold, compare the measured neutron level to a second threshold, and determine information indicative of the presence or absence of fissile material within the interior volume based on the comparisons.
