What is the difference between Bq/m³ and pCi/L?
A. The concentration of radon in air is measured in units of becquerels per cubic meter (Bq/m³) or picocuries per litre (pCi/L). Both these units are measurements of radioactive concentration. The international community uses the becquerel per cubic meter of air (Bq/m³), while the USA uses the picocurie per litre to measure radon. One pCi/L is equivalent to 37 Bq/m³.
