The BetaCheck-106™ provides practical high-reproducibility positioning of detector and applicator for 106Ru applicator measurements in water. The silicon detectors successfully characterized both high and low activity applicators up to 10 mm water depth. The diamond detector proved viable for measurements of the applicator with activity 17.8-18.4 MBq, but it lost stability with depth when measuring the one-year old 8.3 MBq activity applicator.
Dahlander et al. (Wed,) studied this question.
