Radon Gas Ireland, the silent killer, yet unknown by many. Updated situation on Southern Ireland most areas with a high radon count.
The situation regarding radon in Ireland is a significant public health issue, causing around 350 lung cancer cases yearly, as it's the largest radiation source for the Irish population. High-risk "High Radon Areas" exist, especially on granite-rich ground (like parts of Galway, Cork), check the official radon map for high radon count. Testing is straight forward for a qualified specialist and remediation is effective and quick. The Radon map shows a high concentration of indoor radon gas in the red and brown and slightly lower in yellow areas. You will note that all areas are effected by the upper scale.
Overview of radon in Ireland.
-
Radon is a naturally occurring radioactive gas which may be found in high concentrations in indoor environments, such as homes and workplaces.
-
Radon is one of the leading causes of lung cancer.
-
Radon is estimated to cause between 3% to 14% of all lung cancers in a country, depending on the national average radon level.
-
Lung cancer risk is higher for smokers due to synergistic effects of radon and cigarette smoking.
-
Radon concentration indoors can can be detected by BMT as we use advanced meters.
-
BMT use well-tested, durable and cost-efficient methods for preventing radon entry into new and existing buildings.
-
When Radon is detected we can design and install a system to eradicate the problem.
​​​There has been much discussion as to what is a safe level of radon gas in a home. In short, no level is a safe level as radon is a dangerous radioactive gas. Even in properties where the levels are low, the internal environment of a home can effect the buildup of gas. Poor indoor air quality where levels of high humidity creates heavy air layers, especially in basements and under builds, keeping the gas low and allowing a buildup to a dangerous level.
​
Testing for Radon. As so many indoor elements can effect the test outcome, I believe there is really only one way to undertake a radon check professionally, that is with a physical hands on survey. The practice of mailing small cheap chemical censors and asking the home owner to place censors in various rooms then monitoring remotely, is not the answer.
A full property survey is required, both internally and externally. Air quality levels need to be checked to ensure the humidity levers are correct as at a constant value of radon concentration, measured values have been found to increase linearly with increasing humidity, from 30% RH up to a value of ∼85% RH. So any measurement of radon levels in high humidity could be up to 300% inaccurate. Furthermore, I have found that placed sensors and installed smart home monitors can be greatly effected by indoor pollution, such as gasses produced from spores, mould and bacteria.
Radon is a radioactive gas that has no smell, colour or taste. Radon is produced from the natural radioactive decay of uranium, which is found in all rocks and soils. Radon can also be found in water.
Radon escapes from the ground into the air, where it decays and produces further radioactive particles. As we breathe, these particles are deposited on the cells lining the airways, where they can damage DNA and potentially cause lung cancer.
Outdoors, radon quickly dilutes to very low concentrations and is generally not a problem. The average outdoor radon level (1) varies from 5 Bq/m3 to 15 Bq/m3. However, radon concentrations are higher indoors and in areas with minimal ventilation. The highest levels are found in places like under builds, basements, crawl spaces and water treatment facilities. In buildings such as homes, schools, offices, radon levels can vary substantially from 10 Bq/m3 to more than 10 000 Bq/m3. Given the properties of radon, occupants of such buildings could unknowingly be living or working in very high radon levels.
Radon and cancer
As radon forms naturally by radioactive decay inside minerals, part of it escapes into the atmosphere and indoor air, where it becomes a potential hazard to the occupants, exposed mainly through inhalation (Joint Research Centre, 2019). Radon and its decay products are known carcinogens, causing, or contributing to, lung cancer, a risk enhanced by exposure to air pollution and smoking. Although cancer risks from radon are limited to exposure to relatively high and sustained indoor concentrations, radon is one of the leading causes of lung cancer (Ruano-Ravina et al., 2017). 1.2-1.9% of all cancer cases, and 1 in 10 lung cancer cases in Europe may be due to indoor radon exposure (Darby et al., 2005; Brown et al., 2018; IARC, 2018; Couespel and Price, 2020). According to Global Burden of Disease study data, around 19,000 lung cancer deaths in Europe in 2019 may have been due to naturally occurring indoor residential radon (Murray et al., 2020). The risk of lung cancer increases in non-smokers by about 11-16% for exposure to every additional 100Bq/m3 (a measure of exposure to radiation) increase in long-term average indoor radon concentration (Ruano-Ravina et al., 2017; WHO, 2021b). While the association of radon with other types of cancer has been studied, the evidence is still inconclusive.
Although radon comes from natural sources, exposure can be reduced in existing and new buildings, and radon prevention should be considered at the design stage in radon-prone areas. WHO (2021b) lists technical solutions that can significantly reduce radon levels in existing buildings, such as installing a radon sump system, preventing radon passing from the basement into living spaces, sealing floors and walls, and installing special forced ventilation units.
The situation has been made worst by the warming of the climate by allowing easier gas filtration through the drying ground.
Over the last decade, we have noted much higher radioactive meter reading in most homes we serviced. So common were the properties with high readings, its fair to say every home owner should arrange for a radioactive survey test on property in Ireland so book a survey with BMT today.
​
Possible symptoms include shortness of breath (difficulty breathing), a new or worsening cough, pain or tightness in the chest, hoarseness, or trouble swallowing.
Book a full house survey, we are equipped with high grade meters for the detection on Radon. When detected, we have a full range of systems that remove Radon and maintain a safe home.
