Introduction:
Radon, a naturally occurring radioactive gas, poses a significant health risk, particularly when it accumulates in indoor spaces. Its presence can lead to increased cancer risks, particularly lung cancer, and has been recognized as a major environmental concern worldwide. To address this issue, numerous technical solutions have been developed to reduce radon ingress into buildings. This publication aims to provide a comprehensive review of these solutions, encompassing both corrective actions and preventive measures.

Methods, Designs, and Implementation:
The publication begins by discussing the various methods used to reduce radon ingress. These methods include active soil depressurization, which involves venting the radon-laden soil gas from beneath a building and transferring it to the atmosphere. Passive measures, such as sealing cracks and gaps in building materials and installing ventilation systems, are also discussed. The design and implementation of these measures are crucial in ensuring their effectiveness in reducing radon levels.

Materials and Equipment:
In addition to the methods discussed above, the publication also provides an overview of the materials and equipment used in radon preventive and mitigation measures. This includes specialized membranes, sealants, and ventilation systems that are designed to prevent radon entry and promote air circulation within buildings. The selection of appropriate materials and equipment is essential for ensuring the long-term performance and reliability of these solutions.

Measurement of Gamma Radiation:
Measuring gamma radiation from radionuclides in building and construction materials is an important aspect of radon prevention and mitigation. The publication discusses the methods used to measure gamma radiation, including handheld devices and laboratory-based techniques. It also highlights the significance of measuring gamma radiation in determining the radon concentration in different building components and materials.

Reducing Exposure to Gamma Radiation:
Reducing exposure to gamma radiation is crucial in mitigating the health risks associated with radon. The publication discusses various strategies for reducing exposure, including proper ventilation, air filtration, and the use of personal protective equipment. It also emphasizes the importance of educating building occupants and professionals about the risks associated with radon and the measures they can take to reduce exposure.

Target Audience:
This publication is aimed primarily at building and construction professionals who are designing and installing radon preventive and mitigation measures. It provides valuable insights into the latest technologies, methods, and equipment used in radon prevention and mitigation. It is also a useful resource for national authorities responsible for the development of national building codes and implementation of national radon action plans.

Conclusion:
In conclusion, this comprehensive publication offers a thorough examination of technical solutions providing both corrective actions and preventive measures to reduce the ingress of radon indoors. It provides a detailed account of the methods, designs, and implementation of measures to reduce radon entry, as well as the materials and equipment used in these solutions. The publication also discusses methods for measuring gamma radiation from radionuclides in building and construction materials and offers strategies for reducing exposure to this gamma radiation. By targeting building and construction professionals and national authorities, this resource aims to promote the adoption of effective radon prevention and mitigation measures and contribute to the overall reduction of radon-related health risks.
