Many of the nuclear facilities built in the second half of the last century are reaching the end of their lives and are at various stages of being decommissioned. A large part of the industry is now concerned with the decommissioning process and the disposal of resulting nuclear waste. The correct identification and measurement of contaminated (or activated) materials is a vital aspect of this process and poses a major challenge to the industry. Also, correctly classifying waste as 'exempt' as opposed to low level waste (LLW) can reduce such costs by a factor of 50 typically.
