Frequently asked questions

Frequently asked questions

Is radon particularly dangerous for children?

It is commonly known that children are more sensitive to the harmful effects of radiation. However, there is no indication of a specific exposure posing a greater danger to children than to adults. The effects of the radiation caused by radon accumulate through your whole life, and the earlier you minimize exposure to radon, the easier it is to ensure protection from health risks.

What is the cost of radon measurement?

The cost of one radon measurement is around EUR 35–60.

What is the cost of radon mitigation?

According to a survey conducted by STUK in 2012, the average cost of connecting sub-slab suction to radon piping installed during construction was EUR 500 (median). Those who did the work themselves paid EUR 200–300 for the equipment and accessories. Retrofitted sub-slab suction has cost EUR 2,500 on average. Costs incurred from radon mitigation entitle to tax credit for the costs of the work.

Can I do the radon mitigation myself?

Yes, you can also do the radon mitigation yourself. Radon mitigation done without external help is often less costly. Good instructions are available in the STUK radon mitigation guide. Read more on the STUK radon mitigation webpage

Is it necessary to measure radon concentration levels in a block of flats?

In general, it is recommended that the levels are measured in the flats on the lowest floors. It may also be a good idea to measure the levels in the basements of blocks of flats if the inhabitants spend time in them.

Can you sense radon and does it cause any symptoms?

Radon is a gas that is completely invisible and odourless. It cannot be sensed. Radon’s impacts are different from those of, for instance, mould damage, which can be smelled and which may cause symptoms. Radon increases the risk of lung cancer, which is a disease that takes decades to develop. For smokers, radon further increases the likelihood of developing cancer. For non-smokers, the additional risk created by radon is smaller, but not unsubstantial.

How can I find out the radon concentration of indoor air in my home?

The only way to detect indoor air radon is utilizing a reliable method of radon measurement. The boxes are placed at a height of one metre in the bedroom or living room or another part of the dwelling, and they should stay in place for at least two months between early November and the end of April. Using a measurement box is a reliable, simple and affordable method for finding out the radon concentration in your home.

I live in a new/old house, is radon measurement necessary?

We recommend that radon prevention is taken into account already at the construction stage, as it reduces the costs compared to later mitigation measures. However, if you have no information on the radon concentration in the building, we recommend that you measure it regardless of the age of the building.

How can I ensure that my child is not exposed to radon outside of the home?

Parents should ask daycare centres and schools about the radon concentration in their indoor air. STUK has carried out radon monitoring projects at schools and daycare centres. STUK also regulates employees’ exposure to radon at the work place. The local health protection authority monitors the radon in daycare centres, schools and other public buildings for the benefit of children.
