I think Cr-39 good device and good way to measure the concentration of Radon isotope.

Dear Dr. Akrawy

You right if we want to measure Rn-222 but, what about Rn-219?

Fatimh Alshahri

I think RAD 7 is better than CR 39 to measure radon 222 because the error of CR 39 is higher than RAD 7

Dear Fatimh,

Thank you for your answering. Yes you right, but how will separation between them?

John I Garver

Alpha spectrometry is probably the best way. The alpha particles ejected from the two isotopes have different energies. These two isotopes cannot be resolved with CR-39.

Thank you, Dr. Mounir,

Do you mean for active is HPGD, or what you mean?

Thank again
