Abstract:
A detector incorporating about 300 individual counting volumes is described, and the results of performance tests are reported. The device can be employed for a direct measurement of the dose equivalent in an unspecified radiation field on the basis of the lineal energy spectrum in 1-micron diameter tissue regions. It is substantially smaller than a conventional tissue equivalent proportional counter yielding the same counting rate and may be useful for measurements in phantoms.
