is a colorless, odorless, radioactive gas, produced naturally in the
ground by normal decay of uranium and radium. Radon gas is present
in varying amounts throughout the country. Studies indicate that the
result of extended exposure to high levels of radon gas/radon
progeny produce an increased risk of lung cancer.
recommends that the average radon exposure rate not exceed 4.0pCi/L.

Tests and Certifications:
Eperm Detectors: A passive integrating detector used for
measuring radiations (alpha, beta, gamma, and neutrons) and
radioactive gases and vapors (radon, thoron and tritium). Hera Environmental,
LLC. uses e-perm canisters frequently due to the accuracy of the
canisters. They do not collect moisture creating true results. Charcoal Canisters: A passive test
device that does not require electrical current to operate. They are
generally used for short-term testing (approx. 48 hours). At the end
of the test period, the kits are mailed to a regional radon
laboratory for analysis
