side of the system of fig1 the case 11 is shown as being carried in the user 39 s pocket indicated by the dotted lines 12 the inventive monitor 10 comprises a film badge 14 and a rate meter 16 the film badge carries the film indicated at 18 the rate meter carries a suitable known crystal wafer 19 and the associated electronic circuitry 20 these components can be selected for detection of a particular type of radiation such as from 50 kev x ray to 2 mev nuclear sources as required as indicated in fig4 the monitor includes a test switch 24 a test indicating led light emitting diode 25 and an alarm red led 28 as discussed above the rate meter 16 detects instantaneous radiation and the red led 28 lights to provide a visual alarm if a threshold radiation level has been exceeded a long life battery 30 supplies power to the detecting crystal to the electronic circuitry and to the led 39 s the dosimeter film badge 14 which may be a well known type of u201c landauer u201d badge that use a luxel r optically stimulated luminescence dosimeter the landauer badge measures the total radiation to which the user has been exposed over a given period of time thus the monitor 10 can be characterized as including 1 detecting means for detecting radiation 2 processing means coupled to the detecting means for determining radiation dosage and rate of radiation 3 led means coupled to the processing means for indicating undesired levels of radiation and 4.
