Abstract
A detecting unit () detects radiation. A data acquiring block () creates basic data equivalent to the count per unit time of the detected radiation. A data processing block () compares the basic data with a threshold and generates a annunciation control signal when the basic data is above the threshold. An annunciation block () generates a detection sound in response to the annunciation control signal. A computing block () computes the threshold by using a coefficient specified by means of an input device () and the maximum value of the basic data stored in a storage block (). When the user repetitively examines a region () to be measured while gradually increasing the threshold, the region where the detection sound is generated is gradually narrowed. With this, a portion () where radiation is concentrated in the region () can be found out.
