Participant: An organization or individual that has met Program requirements applicable to their specific Program participation and received a proficiency listing.

Performance test: The independent exposure of radon measurement devices in an EPA radon chamber that a Program applicant must analyze accurately to meet Program requirements. Includes both announced Seal Sump Pumps Against Radon and blind tests. Picocurie (pCi): One-trillionth (10 ) of a curie; also equivalent to 3.7 x 10 disintegrations per second, or 2.22 -12 -2 disintegrations per minute.

Picocuries per liter (pCi/L): A unit of measurement of activity per volume. One picocurie per liter is equal to 2.2 disintegrations per minute per liter of air.Primary Services: A classification in the former RMP Seal Sump Pumps Against Radon Program that has been incorporated into the current Analytical Measurement Services category. 

Proficiency Listing: EPA's maintained list of those organizations and Seal Sump Pumps Against Radon individuals meeting Program requirements.(See also Listing).Proficient: Term used to describe a Participant that has met all Proficiency Program requirements.

An applicant chooses to have either the mailing address or Seal Sump Pumps Against Radon business location published.Radon (Rn): A naturally occurring, colorless, odorless, radioactive gaseous element formed by radioactive decay of radium (Ra) atoms. 

The atomic number is 86. Although other isotopes of radon occur in nature, Seal Sump Pumps Against Radon radon in indoor air is almost exclusively Rn-222. The term is often used generically to represent radon and radon decay products in the RPP Handbook.Radon chamber: An airtight enclosure in which radon gas and decay products can be controlled in a stable manner. 

The chamber volume is such that measurements can be made without significantly affecting the concentration within the chamber. Radon measurement service: May include, Seal Sump Pumps Against Radon but is not limited to, consultation (providing information about radon and its risks, providing advice, making recommendations and referrals), packaging radon measurement devices,placing or retrieving radon measurement devices, operating equipment, analyzing or reading radon measurement devices and equipment, preparing measurement results, and reporting measurement results.

Radon Proficiency Programs Information Service (RIS): General Program support service utilizing telecommunications operated by an EPA contractor that provides information and assistance to applicants,participants, the states, and others. 

The RIS is located in Montgomery, Alabama. It can be reached by dialing 1-800-962-4684, by FAX at (334) 260-9051, Seal Sump Pumps Against Radon or via e-mail at mail 10554@pop.net, Monday through Friday, from 9 a.m. to 5 p.m. Eastern Time. RCP Program Individual: (see Residential Mitigation Services) Reapplication / Reapply: 

A process for reentering the Program after failure to meet applicant or Seal Sump Pumps Against Radon participant requirements. Applicants who do not meet the entrance requirements of the Program or Participants who do not meet continuing requirements, will not be included in the Program's Proficiency Listing. 

To be reconsidered for inclusion in the Program listings, Seal Sump Pumps Against Radon the applicant or participant must demonstrate corrections to its methods or procedures and submit proper applications and/or documentation.Relative error: The relative error of a device is the difference between the measured value (MV) and the target value (TV), expressed as MV-TV, divided by the target value (TV).

Request for devices: Notice sent by the RPP Quality Assurance Coordinator (RQAC) to Analytical Measurement Service providers that plan to test with mail-in devices. The request asks for Seal Sump Pumps Against Radon confirmation of the type of device to be tested and is used as a packing slip when the applicant ships the devices to the Program. 

Residential Measurement Services: Radon services provided by an individual in the home that may include, but are not limited to, consultation (providing information about radon and its risks, providing advise, Seal Sump Pumps Against Radon making recommendations and referrals), packaging radon measurement devices and placing or retrieving radon measurement devices in a residential setting.
