I passed my ABR oral exam today after I failed last time. I would like to express my thanks to Adam! This UA-cam channel helped me tremendously, especially during my down time, this was the only material that has never made me to fall asleep. I contacted Adam a couple months ago before my exam and went through about 10 sessions of mock tests by Adam. Not only for the knowledge coverage, but also for the tactics and the recovery of self-confidence. Adam helped me so so much! -Lucy
Adam, I think you got a dose calibrator mixed up with an air filled ion chamber such as the HDR 1000 Plus. The HDR 1000 plus has a 245 cc volume, as you mention, but it is filled with air and vented. Dose calibrators commonly used in NM are filled with Argon at ~12 atm.

Ah, you're right Thaddeus, thanks for noticing! I'll add a note in the top of the descriptor.
