The following words and terms, when used in this chapter, have the following meanings, unless the context clearly indicates otherwise:

Act—The Radon Certification Act (63 P. S. § § 2001—2014).

Acts—The Radon Certification Act and the Radiation Protection Act (35 P. S. § § 7110.101—7110.703).

Firm—A person, other than an individual.

Laboratory analysis—The act of determining radon concentrations in air, water, soil or passive radon testing devices.

Mitigate—To repair or alter a building or building design for the purpose in whole or in part of reducing the concentration of radon in the indoor atmosphere.

Person—An individual, corporation, partnership, association, trust, estate, public or private institution, group, agency or political subdivision of this Commonwealth, another state or political subdivision or agency thereof, and a legal successor, representative, agency or agency of the entities listed in this definition.

Picocurie per liter—2.2 disintegrations per minute of radioactive material per liter of air.

Primary device—Continuous monitors or electrets, or both, read or analyzed, or both, by a primary tester.

Primary tester—A tester who reads or analyzes, or both, the continuous monitors or electrets, or both, that the tester places or retrieves, or both.

Radon—The radioactive noble gas Radon-222 and the short-lived radionuclides which are products of Radon-222 decay, including polonium-218, lead-214, bismuth-214 and polonium-214.

Test—The act of examining a building, soil, air or water for the presence of radon, including taking air, soil or water samples, or the act of diagnosing the cause of radon contamination in a building.

WL—working level—One working level is that amount of potential alpha-particle energy dissipated in air by the short-lived daughters in equilibrium with 100 pCi/1 of Radon-222. One WL is equal to 130,000 Mev of alpha-particle energy deposited per liter of air.
