Description

Passive radon exposimeter: Cheap Radon measurement with film dosimeters!

The passive radon exposimeter is particularly suitable for the short-term determination of indoor radon concentrations. For private households, there are radon dosimeters that work according to the principles of the nuclear track measurement method (DIN 25706-1). These radon dosimeters are absolutely insusceptible to short-term radon fluctuations and thus provide reliable long-term values.

Measuring time: 10 - 14 days

Functionality of passive radon exposimeters

The actual detector - a plastic film of polycarbonate foil (about 1 to 10 cm² in size and about 0.1 to 1 mm thick) - is located inside the exposimeter. The air containing radon gas diffuses through the housing into the measuring chamber; dust, moisture and radon derivatives are retained, however. The sufficiently high diffusion resistance also prevents the thoron (220Rn; half-life: approx. 56 seconds) from entering the measuring chamber. The radon then decays in the measuring chamber, emitting alpha particles, into its short-lived derivatives, which are also alpha emitters. The alpha particles leave traces in the film, which are recorded and evaluated in the laboratory.


Measuring devices (type RSX) for indoor use (radon concentration)

At least two exposimeters are recommended for measurements in single-family houses, which are installed in the lower rooms (ground floor), which are most frequently used (usually living room, bedroom or study). If there are rooms in the basement that are used frequently, then a measurement should also be made there.

Evaluation:

After finishing your measurement, send the passive radon exposimeter back to the certified measurement laboratory. After about 7-14 days you will receive your personal radon report. The costs for the evaluation and the costs for the radon report are already included in the sales price. Therefore, no further costs will be incurred by you (except for shipping costs to the laboratory).
