E-PERM
Radon Starter Kit
With
the basic starter kit, you have all of the testing
equipment needed to handle a business level of about
five homes per week. It includes an instructional
DVD. A set of reference electrets is included with
the kit to verify correct operation of the readout
unit. The kit is very affordable and additional radon
detectors and electrets can be added as your volume
of radon work grows.

The SPER-1E Electret
Reader

The electret voltage reader is a highly sophisticated
electric-field sensor with a special receptacle into
which the electret is placed. When the shutter is
opened, the sensor can read the voltage on the electret
surface without touching it. Readings of the electret
voltage, before and after deployment provide an absolute
number for unambiguous, quantitative determination
of the ion collection accomplished by the electret
due to radon in the chamber.
S Chamber

An electret
is paired with a precision, volumetric E-PERM chamber
to comprise a working E-PERM Radon Monitor. E-PERM
radon chambers are manufactured from electrically
conductive polypropylene. Inlets are filtered to allow
only radon by passive diffusion. E-PERM radon monitors
are also designed to have an insignificant response
to thoron. The S chamber is the most popular because
of these special features:
- Spring-loaded
cap for turning the device on or off
- Hole through
the open stem to allow a 1/8 inch lock tie security
seal
- Hanging ring
on the cap to suspend the device
Electrets

The
electret is a Teflon disk which has been electrically
charged and stabilized.
Short-term electrets with the S chamber will
measure radon at a level of 200 Bq/m3
in approximately 48 hours. A 4 to 7-day test is ideal.
Long-term
electrets with the S chamber will measure radon
at a level of 200 Bq/m3 in approximately
28 days. A 90-day test is ideal. Appropriate chamber
and electret combinations are recommended for high
concentration measurements.

Radon
Flux Monitor
>
Click on the photo for a larger picture
The passive
measurement of radon flux from the ground or other
surfaces used for determining the radon emanating
potential of a building site or to meet regulatory
measurement requirements for uranium mill tailings
or gypsum stacks.
The flux
monitor features a large, diffusion window. The chamber
is vented so that it will not accumulate the radon
concentration. When the E-PERM Flux Monitor is placed
on a radon emanating surface, the radon enters through
the diffusion window and exits through the vents.
The semi-equilibrium radon concentration inside the
camber is representative of dynamic flux from the
surface. The discharge rate of the electret is a measure
of the radon flux. E-PERM Flux Monitors have been
calibrated on the well-characterized radon flux beds
at CANMET (Canada), which are known to produce radon
flux of 7.7 + 1.1 pCi m-2
second -1
(Flux
Units).
