The radiation detector indicates the presence and intensity of radioactivity. The radiation detector can be preset to give a warning signal if the levels of radioactivity rise to dangerous levels. It is a more limited, lower tech equivalent of a neutrino detector. The radiation detector is contained in an ergonomic, handheld case, with a sling for carrying over the shoulder.
