Alpha Spectroscopy Services (Geochronology and Paleolimnology Services)

In particular- Radio isotopic Lead dating - Lead Pb-210 analysis by most frequent method, Alpha Spectroscopy to measure sedimentation rate/sediment accumulation rate to find out age of the sediment (Geochronology and Paleolimnology).

Lead dating - Pb-210 is an isotope in the uranium-238 (U-238) decay series. It occurs naturally throughout the biosphere. Although it can occur in secular equilibrium with its grandparent, Pb-210 concentrations are not constant because geo-chemical processes separate Pb-210 from the longer lived parent isotopes in many systems. This separation and subsequent decay provides the opportunity for the use of Pb-210 as a dating tool.

These cores have come from a diversity of different environments; from the Canadian arctic to the high Andes Mountains. As a result of the diverse and extensive experience Core Scientific International can anticipate and resolve many problems that might occur before the analysis of an individual core is begun.

Gamma Spectroscopy Services

Radon Gas Detection

We are fast and quick service provider for detection of radon gas in residential & commercial buildings in East St Paul, Landmark, Winnipeg, Steinbach in Manitoba and all across Canada. We supply activated charcoal Short term Radon test kit, Alpha track long term Radon test kit and Radon-in-Water test kit.

Radon Rn-222 is a radioactive gas that is colorless, odorless, and tasteless and is impossible to detect without the use of sensitive test equipment. Radon is naturally occuring gas produced by the breakdown of uranium in soil, rock, and water. When allowed to accumulate to high levels, it can be hazardous to long term health. The Surgeon General has warned that radon is the second leading cause of lung cancer.

The EPA presently suggests that corrective action to be taken to reduce the radon levels in your home if measured over the long term at 4 pCi/L or greater.

We provide services for both short-term and long-term detection of radon gas.

Short-Term Radon Detection

Short-Term detection of radon gas is an average of the levels of radon gas over the past seven days. The short-term detection is to monitor short-term fluctuations in the home or commercial building and provide a better feel for problems relating to seasonal and weather related variation in the radon levels.

Long-Term Radon Detection
Long-Term detection of radon is an average of the levels of radon gas that you would be exposed to if you were in the continual presence of the radon levels.

Sandeep Singh has performed many accurate and precise measurements of Pb-210 and Po-210 on standard reference materials (SRMs), measurements of Cs-137, Be-7, radiosotopes belong to Uranium U-238 & Thorium Th-232 series and Radon detection.

Turn Around Period

Core Scientic International is committed to provide high quality services in quick turn around within 1-2 weeks after receipt of samples. Core Scientific International can provide services within a week after receipt of samples if such a requirement.

Cost Estimate
