Abstract
A direct reading detector/dosimeter for neutrons and other high LET radiation is described, comprising a selected, substantially transparent, elastic solid medium uniformly impregnated with droplets of an immiscible detector liquid. The detector liquid-in-solid is appropriately confined and rendered stable for storage by adding a layer of excess detector liquid and sealing in a container. On opening the container and removing the excess detector liquid, the detector liquid droplets become superheated and the detector/dosimeter is activated. Neutrons and other high LET radiation will trigger the vaporization of the superheated droplets and the selected elastic, solid medium will trap the products of vaporization and retain a visual record thereof over an extended time. The number of vaporization events can be counted to give a measure of the radiation dose.
