Radiation Detectors [L17]

[@lucaspaixao826]

I believe that the use of Argon gas in dose calibrators is to increase the photoelectric absorption of photons. As Carlos stated, ionization chambers are not very sensitive to X-rays and gamma photons. The UV light issue in GM counters was new to me, so thanks!

Great lecture! Thanks for sharing! Just a minor comment on slide 11: The pictures show two types of Ludlum Geiger counter / GM survey meter not an "ion chamber" survey meter.

Thank you so much for this masterpiece. Just let me know how much Li should be added to a semiconductor detector to compensate the electron trap events inside it. In case we add Li, how do we know that our electric pulse is coming from radiation or LI?

GOOD JOB. Thank you.
