1. Apparatus for detecting and locating ionizing-radiation sources retained by a tumor in the environment of a body, comprising:
- a probe which can be manipulated by hand,a casing comprising a photodetector capable of producing a response to an interaction of light signals with said photodetector,a signal processor for processing electrical signals coming from said photodetector to provide drive signals, anda warning device which responds to said drive signals by emitting an audibly or visually perceptible output signal in response to said drive signals which are applied to it, whereinthe manipulable probe comprises at least one scintillating optical fiber cladded with an opaque flexible jacket, and provided with a front end and a rear end, the front end being closed by a plug made of the jacket and the rear end connecting said probe to said photodetector in order to convert said light signals emitted by the scintillating optical fiber into said electrical signals.

Abstract
An apparatus for sensing and locating sources of ionizing radiation retained in a turnout in a body environment, including a hand-held probe and comprising a housing with a sensor circuit for outputting a response to interaction between the radiation and the sensor; a unit for processing signals from the sensor circuit; and an indicator responding to driving signals applied thereto by generating an audible or visual output. Said hand-held probe comprises at least one scintillating plastic optical fibre (2) connecting the sensing end to a light sensor (1).
