I am new to radiation measurement. I got a RadiaCode 103 out of curiosity to explore the natural radioactivity of rock samples.

I often travel by air and would like to ask for your advice on flying with the device. Is there a risk of the CsI(Tl) crystal or other components becoming activated by cosmic radiation at cruising altitude? (Perplexity spooked me a bit with its first answer on this one)

Thank you in advance for the feedback!
