LLW waste is measured using a range of techniques depending on the volume and homogeneity of the waste. ANTECH provides a range of options for LLW measurement, which range from far field to segmented. Shielding is sometimes included in measurement instruments to reduce background radiation. Low Level Waste (LLW) upper thresholds vary.
UK – LLW upper thresholds correspond to:
- 12,000 Bq/g (324 nCi/g) for waste with beta-gamma activity
- 4,000 Bq/g (108 nCi/g) for waste with alpha activity
US – The upper threshold for LLW waste with alpha activity is:
- 100 nCi/g (3,700 Bq/g)
NOTE: In the USA, Class C LLW represents waste with higher beta-gamma activity and is generally equivalent to UK ILW with higher beta-gamma activity.
The ANTECH Model G3410-200 LRGS is a transportable Low Resolution Gamma Scanner for the characterisation and measurement of 200L drums of waste. It is capable of characterising waste as Low Level Waste (LLW), Exempt or suitable for ‘free release’.
