Measuring TENORM in Building Materials

CareTac offers breakthrough technology to accurately determine TENORM content (radon and thoron) in building materials such as concrete, bricks, gypsum, and other building materials, and to establish the rate of TENORM emanation over the entire lifecycle of these building materials.

Testing Advantages

  • Know the TENORM content in your building materials

  • Incorporate mitigation solutions to minimize TENORM exposure risks throughout a building's lifetime

  • Save money on TENORM mitigation measures that would otherwise have to be implemented later on and cost significantly more.​

  • Increase usage of fly ash, slag, and other coal combustion products (CCP) to improve building material durability and cut CO2 emissions.  

  • Improve compliance with international standards and regulations

  • Make your building more appealing to buyers and tenants

Testing process

  1. Measurements

    • Materials are measured in a hermetically sealed chamber. The time necessary to obtain a highly accurate measurement depends on how radioactive the materials are. ​

  2. Data analysis

    • We employ highly complex mathematical equations developed meticulously over years of trial and error to process the generated measurements and produce ​precise results.

  3. Porosity effects​​​

    • Our CT tomography industrial scanning system helps to provide a detailed understanding of the rates at which radon and thoron will emanate from the materials over the life time of the structure, building, etc. that they will be used in. 

  4. Consulting​

    • Our expert consultants use the data obtained to advise builders, constructors, and other clients on what options they have based on the test results and what is ideal from a health, economic, and quality standpoint. 

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:

  • Fly ash,

  • Bottom ash,

  • Boiler slag, and

  • Flue gas desulfurization gypsum.

These CPP are an affordable and abundant way to manufacture concrete and other building materials. 

The Greater the CCP, the Greater the Radiation Hazard​

The problem with the increasing role of coal combustion products (CCP) in building materials is that this increases the TENORM 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, CCP is becoming hugely popular in concrete for housing, thus drastically increasing the TENORM hazard for the people that live in these homes

CareTac can help determine the risk that TENORM in these building materials pose and allow to take the proper steps to mitigate them. After all, TENORM exposure is an entirely fixable problem, if addressed in a timely and proper manner. With CareTac's testing technology, you will save money and, more importantly, lives.
