Tips for radon measurement with RadonTec PRD Exposimeter

Meaningful radon measurement in single family houses

In order to carry out a meaningful radon measurement in single-family houses, with which also an annual average value can be determined

• at least two (2) living rooms should be measured (e.g. bedroom, children's room, living room).
• at least one (1) living room per floor should be measured.
• should the length of the measurement period be between 3 and 12 months. Those who cannot wait 12 months should observe the minimum measuring time of 3 months (min. 88 days) during the heating period (October - April) in order not to underestimate the annual mean value.
• each single-family house must have its own measurement package.
• the measuring instructions must be followed exactly.

The cellar as a cause of increased radon concentration

Radon-containing soil air primarily enters the building through leaks in the basement. Typical entry points are e.g. cable and pipe penetrations, cracks in the floor slab, leaking drains or other openings to the ground. Usually the highest radon values are to be expected also here. The so-called chimney effect creates negative pressure in the house, which sucks radon-containing soil air through the above-mentioned leaks into the interior of the building. Then the radon gas spreads further to higher Floors.

Measure all cellar rooms at the same time. This is a simple and inexpensive way to determine which cellar rooms are causally related to elevated values on the upper floors. This mapping helps to determine the entry paths and the derivation of appropriate renovation measures.
