Patent ID: 8642971

Claim:
A neutron dosimeter with (a) a neutron moderator ( 12 ), (b) a first radiation detector ( 14 ), which is arranged in the neutron moderator ( 12 ) and surrounded by a first metal body ( 28 ) comprising a silver foil, (c) a second radiation detector ( 16 ), which is arranged in the neutron moderator ( 12 ) in the direct vicinity of the first radiation detector ( 14 ) and is surrounded by a second metal body ( 30 ) comprising a tin foil, (d) wherein the first metal body ( 28 ) and the second metal body ( 30 ) are designed such that they substantially have the same photon absorption, and (e) an evaluation circuit, which is connected to the radiation detectors, (f) wherein the evaluation circuit is designed to suppress electric pulses that are caused by ionizing radiation and have a pulse height that is below a prescribed pulse-height threshold.
