Construction Materials Testing
Measuring Radon and Thoron in Construction Materials
CareTac offers unique technology to accurately determine the radon and/or thoron content in construction materials such as concrete, cement, granite, aggregate, bitumen, and others, and to establish the rate of radiation emanation over the entire lifecycle of these building materials.
Our technology lets our clients know the radon and/or thoron content in their construction materials and incorporate mitigation solutions to eliminate any threat of lung cancer throughout a building's lifetime, while saving money on mitigation measures that would otherwise have to be implemented later on.
We can test:
Concrete, cement, brick, gypsum, soils and aggregates, and more.
Price: R 2,000 per sample (300 grams). Prices in USD and Euro available upon request (ex. for clients outside South Africa).
Full testing includes:
Radon and thoron in-air emanation rates
Gross alpha and beta radiation measurements
Surface gamma radiation screening
Comprehensive technical report
Unique Technology for a Multibillion Dollar Industry
Countries around the world, especially South Africa, are turning more and more to Coal Combustion Products (CCP), by-products of coal production that allow to increase recycling over landfilling. CPP including the following:
Boiler slag, and
Flue gas desulfurization gypsum.
These CPP are an affordable and abundant way to manufacture concrete and other building materials.
With the vast majority of its energy generation coming from coal, South Africa's coal power plants produce an abundant supply of CCP that building material manufacturers are incorporating more and more into their products as a means to increase strength without adding weight.
The Greater the CPP, the Greater the Radiation Hazard
The problem with the increasing role of CPP in building materials is that this increases the radon and thoron content in them, thus increasing the radiation-exposure hazard for those in the buildings, factories, facilities, and other structures that use these materials. In South Africa, CPP is becoming hugely popular in concrete for housing, thus drastically increasing the radon and thoron hazard for the people that live in these homes
CareTac can help determine the risk that these building materials pose and allow to take the proper steps to mitigate them. After all, radon and thoron exposure are entirely fixable problems, if they are addressed in a timely and proper manner. With CareTac's testing technology, you will save money and, more importantly, lives.
