Trace Radon 222 Testing for Natural Gas, LNG, and more.

Radon Analysis for Natural Gas

Trace Radon 222 Testing for Natural Gas, LNG, and more. 

SGS helps natural gas producers, distributors, and processors monitor Radon 222 levels in methane (natural gas) and other light hydrocarbon production gases. 
Trace levels of Radon 222 can be present in natural gas production due to natural geological decay processes. Radon will flow with natural gas through the oilfield, in pipelines, in powerplants and LNG facilities. Measuring the amount of Radon in natural gas helps you understand and take appropriate action to limit exposure to nat-gas production employees, power-plants, storage tanks, and end-users who use natural gas for heating and cooking.    

After radon undergoes radioactive decay, the radon decay products attach to airborne particles and ultimately can form thin radioactive films on the inner surfaces of natural gas processing and storage equipment. Radon is constantly entering with the feed natural gas, allowing the build-up of radon decay products inside the equipment over time. Radon 222 isotope measurement is available for natural gas samples taken along the entire supply chain - - well-heads, pipelines, processing units, storage tanks, ships, and more. 

Radon sampling, testing, and monitoring programs for natural gas customers is SGS are available. Trained SGS personnel help nat-gas customers manage Radon content concerns. A minimum of a 10L gas sample is taken. Larger sample sizes are acceptable, if available.  

The use of alpha spectrometry instrumentation offers an advantage in onsite ‘sample sniffing’ and ‘sample grabbing’ applications. Both onsite and offsite radon laboratory analysis are available, depending upon requirements. 

The Radon ‘sniff test’ provides quick measurement for indoor Radon inspection, usually 3 sniff tests are run to obtain more accurate results. For normal gas measurement, SGS uses a ‘sample grab’ protocol with a cycle time of 5 minutes. If the radon concentration is low the cycle time can be extended to 1 hour to increase accuracy.
