With a large-scale study, the Hessian Radon Center (HeRaZ) wants to provide information about the radioactive noble gas and at the same time investigate the concentration of the gas in private houses in Hesse. The participants will be sent measuring devices free of charge so that they can measure radon at home for a year. The data from 3000 households in Hesse are to be determined and then evaluated. The Hessian Ministry of the Environment is fully financing the campaign.

The aim of the study is to find out how much radon is in Hessian residential buildings, which houses tend to have a higher concentration and how the data ultimately fit with the existing radon potential map, which reflects the radon concentration in the soil.

Residents of both houses and apartments can participate. Since the handy measuring devices (exposimeters) measure passively, nothing more needs to be done than waiting. After the measurement period, the devices are sent back and evaluated. The participants will receive their personal evaluation free of charge. In addition, the HeRaZ is available to advise you on whether you should do something about the radon and what protective measures are appropriate for you.

Since radioactive radon is everywhere in the ground, it affects everyone equally. It occurs in different concentrations depending on the region, but evaporates quickly in air. However, whether and how much accumulates in your own home can only be determined by taking measurements in the living areas. Anyone who is exposed to the gas in high concentrations for a long time has an increased risk of developing lung cancer. Methods of counteracting excessive exposure range from increased ventilation to conversion measures.

At the start of the campaign, the participants will receive an email with the link to the shop for the measuring devices. Online form for pre-registration,
