Abstract
A dosimeter for detecting high-energy neutron radiation having a neutron converter and a detection element is proposed which is characterized by the neutron converter comprising metal atoms which convert the energy of the neutrons into protons, alpha particles and other charged nuclei in a suitable energy range so that they are detectable.
Claims23
A dosimeter comprising:
- (a) a neutron converter comprising
- metal atoms which convert high-energy neutrons to be detected into protons, alpha particles and charged particles in a suitable energy range so that they are detectable, wherein said metal atoms of the neutron converter are stable in the sense of radioactivity;
- a hydrogenous material which converts fast neutrons to be detected into protons;
- a material suitable to cause a (n, α) reaction and/or a (n, p) reaction to convert low-energy neutrons to be detected into protons and/or alpha particles;
- and
- (b) a detection element for detecting and registering said protons, alpha particles and charged particles as produced by said three converting processes;
- wherein the dosimeter is operative for detecting high-energy, fast and low-energy neutrons.
