RAP-47というCsI (Tl) シンチレーションプローブはγ線とX線を拾う。かなりエネルギーの低いγ線やX線を拾うことができる。その範囲は20〜80KeVが最適という前例がある。
制動X線エネルギーも拾えるのだろうか。また、このリストには無いが放出率はどれくらいだろうか。

When K-shell vacancies are filled by a higher shell electron, energy is liberated in the process as either an X-ray or an Auger electron. The following is a listing of each element and its atomic number, followed by (in order) the K-alpha, K’-beta-1 and K’-beta-2 x-ray energies (in units of thousand electron volts, or “keV”), as applicable
