Evaluation and measurement of 55Fe radioactivity in accelerator hardware activated at high energy accelerator facilities
It was indicated that 55Fe (EC decay, half-life: 2.7 y) is the most abundant radioisotope in the residual activities formed in hardware composed of iron and steel at high energy accelerator facilities. Its approximate activity could be evaluated on the basis of an integrated neutron flux measured by an activation method using a copper threshold detector. Both a low energy photon spectroscopy and a liquid scintillation counting method were confirmed to be applicable to 55Fe measurement with high sensitivity.
