A Stack Effluent Radioisotope Monitor

The transmission of sub-millimetre radiation by copper light pipes

“…The disparity between theoretical prediction and practice has been much investigated and discussed, particularly with reference to longer wavelengths in the mm and cm ranges. Harvey (1959) reports that at 1.07 mm, the measured attenuation in coin silver waveguides was 1.6 times that calculated and this increased to a factor of 1.75 at 2.1 mm. Benson (1969) discussed many of the findings and the possible reasons as to why much greater losses are experienced in practice.…”

MonitoringforAir-Borne Radioactive Materialsat Hanford Atomic Products Operation

“…One system combining a strip filter monitor and an air scrubber has been developed at Hanford by the Radiation Instrument Development Operation. 12 In this monitor (Figs. 4 and 5), a rnetered flow of stack gas sample passes first through a continuously moving strip filter and then through a counter-current flow caustic scrubbing column.…”

Nucleonics

“…A stack effluent radioisotope monitor has been used by Harvey (448). The apparatus and the techniques employed are described and some of the experimental data obtained are also reported in that article.…”
