Alpha Spectroscopy 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, 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.

Core Scientific International has an opportunity to provide services to Univ. of Mary Washington, Dept of Earth Science and Geology, Fredericksburg, VA, USA, University of Arkansas, Fayetteville, AR, USA, Director Archaeological Research, Dept. of Anthropology, Univ. of Denver, Denver, Colorado, USA, Ecology and Environment, Inc. International Specialist in the Environment, Seattle, WA, USA. Core Scientific International use well-tested procedures in their lab work. These procedures have been used to analyze sediment, sand & peat for Pb-210 analysis in more than 300 cores, with several thousand samples and related quality control samples during the past 10 years by Sandeep Kaur Singh at private Research Organization. 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.

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 detector.

The Health Effects of Radon

In the open air, the amount of radon gas is very small and does not pose a health risk. However, in some confined spaces like basements and underground mines, radon can accumulate to relatively high levels and become a health hazard. Exposure to high levels of radon has been associated with an increased risk of lung cancer, depending on the time length of exposure.

Because it is radioactive, radon decays. As it decays, it produces decay products, sometimes called "radon daughters" or "radon progeny". Two of these progeny, polonium-218 and polonium-214 decay rapidly themselves, and emit alpha particles. When alpha particles hit an object, the energy in them is absorbed by the surface of the object. Human skin is thick enough to not be affected, but if you breathe in alpha particles, they can damage bronchial and lung tissue, and can lead to lung cancer.

Studies of the incidence of lung cancer among uranium miners showed a correlation between radon exposure and deaths from lung cancer. Until recently, there had been no evidence of a direct link between radon levels in the home and lung cancer. However, two recent independent scientific studies in Europe and North America show that lung cancer risks extend to levels of radon found in some homes.

Radon in the Home

Radon gas can move through small spaces in the soil and rock upon which a house is built. It can seep into a home through dirt floors, cracks in concrete, sumps, joints, basement drains, under the furnace base and jack posts if the base is buried in the floor. Concrete-block walls are particularly porous to radon and radon trapped in water from wells can be released into the air when the water is used.

A survey conducted by Health Canada in the 1970s showed that radon levels in certain Canadian cities were higher than in others. However, these same studies showed that it is impossible to predict whether any one house will have a high level of radon. Factors such as the location of the house and its relation to the prevailing wind may be just as important as the source of the radon.

radon detection

The only way to find out if a radon problem exists is properly performed radon test within the house .

Radon information

It is colourless, odourless, tasteless and radioactive. Next to cigarette smoke, radon is the leading cause of lung cancer. It comes into our homes naturally from uranium in the soil. Radon is a naturally occurring gas that enters buildings from the surrounding soil.

Why is Radon Important in Manitoba



Manitoba's soil contains widespread uranium that supplies a constant source of radon. Our houses are built so that radon is likely to enter into the basement space. Air pressure within our houses is less than that outside. This causes radon to be sucked in from the gases in the soil.

Radon and lung cancer



The breakdown of the radon releases radiation as "alpha particles" which can damage the soft tissue in our lungs. Damage of this nature can change the cells in the soft tissue and this change may lead to lung cancer.

Radon mitigation

Mitigation is the formal name for steps taken to eliminate radon from home air.

The following products are used to reduce the radon level

Floor drain seals: $45 +taxes

They allow water to flow down the drain but block the upward flow of radon. The valves are a 19 cm diameter. These seals are designed and manufactured by Dranjer, a local Winnipeg company. These circular PVC seals cement into the concrete at the floor drain in your home basement.

Sump pump seals: $45 +taxes

They are fitted to a sump pump cover. They are 12.5cm in diameter. These valves are also manufactured by Dranjer and are similar to the floor drain valves

Small floor drain seals: $35 +taxes

These Dranjer Model F-R2 have a flexible rubber ring which allow it to fit a variety of small areas. Its versatility will allow it to fit a drain which has a diameter of 20cm down to a smallest diameter of 5cm. These seals fit under the floor drain cover which is then put back in place. It requires only silicone caulking for a sealant which makes for an easy install to fit smaller areas in the floor

How does radon enter buildings?

Radium in the soil directly under a building is normally the major source of indoor radon. Less important sources of radium are in ground water and building materials.
The presence of uranium in soil and rock is an important indicator of places where radium and radon can be present. Because radon is a gas, a fraction of the radon produced in the soil can find its way into a building. The rest is trapped in the soil. In the air, radon decays to radon daughters that are solids, and are present in the building air as fine particles.
The concentration of radon and radon daughters in the indoor air depends on:
the amount of radium in the soil and the ease with which the radon it produces can move through soil and building walls where it can then mix with the room air. Because radon is a gas, changes in the atmospheric pressure also affect its emission from the ground and its accumulation in the building air.
The concrete floor and walls in the basement slow down the movement of radon from the soil into the building. However, cracks in the floor, wall slab joints, and the drainage system allow radon to enter a building.
Indoor radon concentrations are almost always higher than outdoor concentrations. Once inside a building, the radon cannot easily escape. The sealing of buildings to conserve energy reduces the intake of outside air and worsens the situation. Radon levels are generally highest in cellars and basements because these areas are nearest to the source and are usually poorly ventilated.
