PROBLEM TO BE SOLVED: To make a radiation meter to be provided with both a detector which electrically detects radiations and another detector which nonelectrically detect radiations. SOLUTION: A semiconductor sensor 22 is provided in the main body 12 of the radiation meter and a film 34 is provided in a clip 14. Usually, the measured results of the sensor 22 are read and, when the confirmation of the measurement reliability and operations of the sensor 22 becomes necessary, the film 34 is developed. It is also possible to provide the sensor 22 on the clip 14 side and the film 34 on the main body 12 side.
