Insert a new filter in each of the two E-RPISU chambers

Radon decay products which emit alpha particles that cause electret voltage to decrease are collected on a filter (thus allowing for measurements of RDPs).

Measure voltage of standard Rad-Elec electrets

The E-RPISU system uses proven Rad-Elec technology. This allows you to use a common reader for several E-RPISUs as well as other Rad-Elec measurement devices.

Place electrets in chambers

Electrets are placed in each chamber (1 radon and 2 RDP). Electrets can be either S or L electrets depending upon estimated expsoure.

Place device and plug into outlet

Follow standard protocols for short-term tests. Typical use is 2-3 day measurement duration.

Open chambers

Opening the chambers and adjusting the air flow is all that is needed to start the test!

Enable security features if needed

There are tamper resistant locks that can be used to keep chambers open, air flow set, and cover open. A run time clock is also incorporated to identify if occupant unplugged unit.

Retrieve the device and close chambers

Bring device back to your lab to measure final voltage of electrets.

Measure voltage on electrets

The difference in voltage, operation of the time device, and measurement of air flow rate, allows one to determine radon and radon decay product levels in area tested.

Access PGL Website and enter data

Record voltages, address, air flows. All it takes is about 5 minutes and the report is done! You can also access your previous tests for review or regeneration of reports.
