Radon

Backgroundradon graphic

Radon is a naturally occurring radioactive material (NORM) usually present at trace levels in natural gas. The radon migrates into the gas from the formation rock surrounding the reservoir. Radon-222 (222Rn) has a half-life of 3.82 days and it is therefore crucial to determine its activity on site.

Key Features

Qa3 perform on-site Radon activity determinations by alpha spectrometry. The achievable LOD for Radon activity in natural gases is 30 Bq/m3. Whilst the quantification of radon activity provides an early indication of potential NORM levels within the production system, in order to draw firm conclusions this analysis is usually carried out in conjunction with sampling of additional stabilised fluids for subsequent NORM determination at a specialist radioanalytical laboratory facility.
