Emission Chambers

Soil and Hard surface emission detection

Two emission chamber accessories are offered for the RAD7 radon detector: one for soil surfaces and one for hard surfaces. The Soil Surface Emission Chamber has a stainless steel skirt around the circumference, to penetrate the soil. The Hard Surface Emission chamber has a flat base with sealant.

For soil emission measurements, the skirted chamber may be placed on the ground and stood upon, to push the steel skirt into the dirt. A closed loop measurement may be completed in approximately 30 minutes. Open loop monitoring may be performed continuously, showing diurnal variation of soil emission and allowing the user to obtain as high a precision as desired.

For hard surface emission measurements, the chamber without the metal skirt, and with a soft seal instead, may be applied to the surface. Closed and open loop measurements may be made.

Closed loop protocol provides a quick and sensitive reading, while open loop offers increased scope for investigating variations in emission due to changes in parameters such as barometric pressure, temperature, relative humidity, and ambient radon concentration.
