Abstract
A data collection device includes a housing and a data collection unit located in the housing. A power unit is located in the housing and is operably connected to the data unit to provide power for operation of the data unit. An irradiation sensor is located at the data collection device to detect exposure of the data collection device to irradiation. An irradiation sensor includes a thermal energy absorbing material and a thermal energy sensitive material in thermal communication with the thermal energy absorbing material. The thermal energy sensitive material is characterized by a change in color when exposed to a selected degree of thermal energy due to irradiation.
