calibration of ion flow chambre!

Milentije

I need to calibrate ion flow chambre,dont know exactly how.
I dont know also how to relate Bq/m3 to doserate mSv/h.
Are there any doserate limits,instructions suggest that there are.

Instruction for calibration of any radiation survey instrument can't really be done on the internet, since it requres some kind of source to calibrate the instrument with (typically, a Cs-137 sealed source or other long-lived nuclide). This requires training commensurate with the hazards associated with handling such material. As for conversion of Activity per unit volume to dose rate, that all depends on the nuclide in question. The higher the energy of the radiation, the greater the dose rate (given the same activity). If you want to learn more, you might want to google search "gamma constant" or "exposure constant".
