THE RADIOMETRIC METHOD

THE RADIOMETRIC METHOD

The radiometric method is affected by meteorological variations. Principally the radioactive radon gas that forms a background level can be blown about by wind and it is also influenced by barometric pressure and temperature. Rain can wash the gas out of the air and so background may be reduced for a time after rainfall.
