RAD ELEC ERPISU
The device that measures radon decay products or progeny concentration is called an Electret Passive Integrating Progeny Sampling Unit (E-RPISU®).

The E-RPISU
® is basically composed of an air sampling pump, a flow meter and an electret ion chamber with an appropriate filter holder and an electret.



HOW IT WORKS
An air-sampling pump (0.5 to 2 liters per minute) is used to collect the radon decay products for a known sampling time on a 3.5 cm2 filter sampler mounted on the side of an electret ion chamber. The flow rate can be adjusted to the recommended rate of 0.5 to 1 liters per minute. And sampling duration 1 to 7 days. The filter paper is mounted such that the progeny collected emit their radiation into the interior of the chamber. The alpha radiation emitted by the progeny collected on the filter ionizes air in the electret ion chamber. The ions are continuously collected by the electret, providing integrated alpha activity collected on the filter paper. The standard electrets and the readers used in E-PERM® System are usable with this unit. The initial and final readings of the electret, the flow rates and the duration sampling (as recorded by the time totalizer) is used in a software to calculate progeny concentration in WL units. Software is provided for data analysis.
