Transmission detectors for cyclotron in-vivo irradiations with neutrons. 1975

K V Ettinger, and B J Thomas, and O J Filkin

The neutron fluence imparted to the irradiated subjects needs to be measured accurately in order to obtain meaningful results from diagnostic irradiations. A convenient neutron detector for this purpose is in the form of a transmission chamber, which covers the whole beam directed at the subject. In one design the detector is an ionization chamber, filled with propane gas, in another a thin sheet of plastic scintillator is coupled to a pair of photomultipliers.

UI MeSH Term Description Entries
D009502 Neutrons Electrically neutral elementary particles found in all atomic nuclei except light hydrogen; the mass is equal to that of the proton and electron combined and they are unstable when isolated from the nucleus, undergoing beta decay. Slow, thermal, epithermal, and fast neutrons refer to the energy levels with which the neutrons are ejected from heavier nuclei during their decay. Neutron
D013679 Technology, Radiologic The application of scientific knowledge or technology to the field of radiology. The applications center mostly around x-ray or radioisotopes for diagnostic and therapeutic purposes but the technological applications of any radiation or radiologic procedure is within the scope of radiologic technology. Radiologic Technology,Technology, Radiological,Radiological Technology
