IAQ & Radon

CareTac provides comprehensive Indoor Air Quality (IAQ) and radon testing for homes, businesses, and industrial facilities, as well as testing of construction materials. With a host of radon testing techniques, our customers can find a solution that works ideally for them.

Long-term passive testing

A tried-and-true industry technique to test radon-gas levels using PARC RGM detectors. 


Short-term onsite testing

We rely on the RAD7 by DURRIDGE to perform highly accurate, onsite radon and thoron measurements in just minutes for clients with special needs or who just want to know as soon as possible what radon health risks they may be facing.


Continuous digital testing 

CareTac is an authorized distributor for Airthings, the world leader in continuous electronic Indoor Air Quality (IAQ) and radon monitoring.

Radon mitigation system design and installation

CareTac's experts can design and install customized and affordable radiation mitigation systems that are guaranteed to drastically reduce radon health risks.

Building Materials Testing Synchronization

Building Materials Testing Synchronization technology - BMT Synch - features the unique ability to quickly, economically, and accurately collect and synchronize crucial NORM data in building materials (concrete, cement, gypsum, brick, etc.) and coal combustion products (pulverized fly ash, blast furnace slag, etc.) to ensure optimal economic, health, and environmental results.  

1. Radon and thoron concentrations

BMT Synch determines radon and thoron concentrations in almost any building material.   

2. Radon and thoron life-cycle exhalation

BMT Synch pinpoints the amount of human exposure to radon and thoron over a building's  lifetime.

Radiation Services 

CareTac wields unique capabilities and expertise in radiation and nuclear safety and security solutions. We are able to provide fully customized solutions for clients across South Africa in radioactive material transport and storage, radwaste management, decommissioning, and more

CareTac provides training sessions and workshops for companies in South Africa looking to improve their compliance with South African and international radiation and radioactive material requirements, as well as looking to improve their own radiation and nuclear competences.


By becoming fully compliant, companies in South Africa improve their bottom line, give their employees safer working environment, and avoid costly violations while providing a positive effect to their social reputations both nationally and internationally. 

CareTac can conduct either ready-made courses or create tailor-made solutions for clients with specific goals. Moreover, we can provide your course either online or in person, whichever is most convenient and cost effective for our clients.
