The self-absorption of the 662 keV gamma radiation in a spent nuclear fuel assembly rod (ie fuel material and cladding) has been determined experimentally and theoretically. The measurements were performed inside a beta-gamma hot cell, using a shielding monitor which incorporates a miniature planar CdTe detector. An agreement within 2% has been observed between the experimental and theoretical mass absorption coefficient at 662 keV.
