Abstract
When the distal end of a radiation detection probe () is directed toward a place to be measured, pointer light emitted by a light-emitting device () sequentially passes through a transmission window (C) of a radiation detection element () and a projection window (E) of a probe cover () to be emitted onto the place to be measured. This pointer light clearly indicates the place as a bright spot. The radiation from the place passes through the distal end of the probe cover () to be collimated by a radiation-introducing window (A) of a side shield (), and then enters the radiation detection element (). The dose of the radiation is detected in this way.
