Radiological Laboratory
We measure radioactive isotopes in water, soil and environmental matrices for environmental monitoring, public-health protection and regulatory compliance, serving the Kingdom and the Gulf states, with stated detection limits.
Analytical techniques and detection limits
Alpha spectrometry
Identifying alpha-emitting isotopes — U-234, U-238, polonium-210 and thorium-232 — in water and environmental samples. The isotope is separated on a strong anion exchanger, electrochemically deposited on stainless-steel discs, then measured by alpha spectrometry. The minimum detection threshold is below 10 mBq per sample.
Gamma spectrometry
A 40% HPGe detector measuring gamma emitters such as caesium-137, caesium-134 and potassium-40, across photon energies of 60–2000 keV, with detection limits of 10 pCi/L for caesium-134 and 20 pCi/L for caesium-137.
Gross alpha and beta
A screening method counting total alpha and beta particles to decide whether detailed analysis is needed. It uses a proportional gas counter with P-10 gas (90% argon, 10% methane), detecting alpha above 3 MeV and beta above 0.1 MeV.
Radon-222
A naturally occurring radioactive gas from radium-226 decay, associated with lung cancer when it concentrates in enclosed spaces. It is measured through the alpha particles emitted by polonium-218 at about 6.0 MeV, over a range of 0.1 to 20,000 pCi/L.
Purposes of radiological analysis
Environmental monitoring
Tracking radioactivity in environmental matrices over time.
Public-health protection
Early detection of what may reach people through water or air.
Regulatory compliance
Reports documenting a facility's compliance for submission to regulators.
