Radon Mitigation >> Start A Radon Testing Business

PROGRAM REQUIREMENTS FOR MEASUREMENT SERVICE PROVIDERS Adherence to all of the following requirements constitutes an EPA-conforming measurement.Participants involved in measurements for real estate transactions must also follow all procedures described in this section (Section 4.2), as well as those Start A Radon Testing Business in EPA's Protocols for Radon and Radon Decay Product Measurements in Homes (EPA 402-R-92-003). 

See Exhibit 3-1 for a summary of the RPP requirements applicable to measurement service providers.4.2.1 Develop and Implement a Quality Assurance Plan (QAP) All analytical measurement Start A Radon Testing Business service and residential measurement service participants are required to develop, operate by, and maintain QAPs throughout their participation in the Program. 

This is both an entrance and a continuing requirement. Participants with analytical capabilities must have a QAP that is appropriate Start A Radon Testing Business to each device listed for the company. The QAP must be updated whenever a participant applies to add a device to a listing. A QAP must provide details, practices, and procedures unique to devices used by the participant to provide radon measurement services. 

Residential measurement service providers must have a QAP that is appropriate to any device they use to provide consumers with radon measurement services.The QAP can be that of the residential service provider's employer or the analysis service provider.At a minimum, QAPs developed by analytical measurement Start A Radon Testing Business service providers must address all four of the elements highlighted below. 

QAPs developed by residential measurement service providers that do not partake in any analytical services do not need to have a calibration section, however, Start A Radon Testing Business the QAP must address the three remaining topics mentioned below. The EPA will emphasize these elements when reviewing and approving a participant's QAP: 

Chain of Custody: The QAP must demonstrate Start A Radon Testing Business custody procedures for tracking specific measurement devices. All measurements performed in accordance with EPA procedures should have supporting documentation which provides complete chain-of-custody information including RPP identification number of the analytical and residential measurement service providers. 

Residential measurement service providers must keep a record of all analytical measurement Start A Radon Testing Business service providers that they use.This record should document the device(s) used and the RPP ID number of the EPA listed analysis provider. EPA listed devices must each carry a unique identifier, such as a serial number. 

Analytical measurement service providers must keep a record of the EPA listed residential measurement service providers whose devices they analyze,Start A Radon Testing Business and specific to the devices analyzed. Calibration: Participants should describe their procedures and schedule for calibration. This ensures that results of analyses are accurate within acceptable limits and indicates when corrective actions should be taken. 

All continuous radon and continuous working level measurement devices must display calibration information. At a minimum, Start A Radon Testing Business this calibration "label" should list the calibration facility, the calibration date, and the calibration expiration date. Calibration certificates or logs mustbe maintained for all devices covered by EPA listings. 

Proof of calibration may be requested byEPA—separate from the QAP—at any time following Start A Radon Testing Business Program application. Checks for Background: The QAP should include instructions on how to assess the effect of background radiation on measurement results. 

Spiked, Blank and Duplicate Samples: Depending on the measurement device or method, a QAP must include regular use of one Start A Radon Testing Business or more of these checks for bias and precision. Spikes are samples that are exposed to a known radon concentration. Blanks are unexposed samples. Duplicates are two or more measurements with identical equipment exposed over the same time interval at the same location.

In addition to these basic elements of a QAP, EPA has developed more specific guidance to assist measurement service providers, Start A Radon Testing Business as described in Radon Measurement Proficiency Program: Guidance on Quality Assurance, EPA document 402-R-95-012. This document provides guidance on quality control measurements, data analysis, and the required elements of acceptable QAPs. 

Participants can adopt EPA's QAP or use it as a model in developing their own QAP. In case of future revisions, Start A Radon Testing Business participants are responsible for obtaining the Agency's revised QA/QC guidance and method-level protocols as they are issued. Participants are also responsible for adjusting their QA/QC plans as necessary to remain consistent with Agency-issued documents as well as changes in their own procedures and technology.

The Agency reserves the right to conduct an on-site audit or Start A Radon Testing Business make information requests to ensure that the participant actually adheres to its QAP on a day-to-day basis.4.2.2 Have and Use Standard Operating Procedures (SOPs)The use of acceptable standard operating procedures is both an entrance and continuing requirement of the Program. 

All analytical measurement service providers must have a written, device-specific SOP in place for each radon measurement device for which they are listed. Analytical Start A Radon Testing Business and residential service providers must either develop their own SOP or use the manufacturer-developed SOP for each of their devices. Applicants and participants are required to provide a copy of their SOP(s) to EPA upon request at any time after submitting an Application.

An SOP must include specific information on how to operate and/or analyze a particular measurement device. The SOP must be consistent with the applicable EPA radon measurement Start A Radon Testing Business protocols referenced in Section 4.2.3.The Agency reserves the right to conduct an on-site audit or make an information request to ensure that the participant actually adheres to its device-specific SOPs on a day-to-day basis.4.2.3 

Follow EPA Radon Measurement Protocols All RPP Start A Radon Testing Business participants that provide measurement services must follow EPA radon measurement protocols contained in the Indoor Radon and Radon Decay Product Measurement Device Protocols (EPA 402-R-92-004)and Protocols for Radon and Radon Decay Product Measurements in Homes (EPA 402-R-92-003). 

The former document states device handling protocols specific to the device measurement method (e.g., activated charcoal adsorption, alpha track detection, etc.). The latter document cites protocols specific to device placement during real estate testing. Together, Start A Radon Testing Business these protocols provide technical support for the Agency's radon policy and guidance to consumers. 

Both of these documents can be obtained from the National Technical Information Service (NTIS) (see Appendix B for more information on all Program documents). Participants that do not adhere to these Protocols are subject to delisting from the Program and Start A Radon Testing Business will be deleted from the ProficiencyListings. This is a continuing requirement of the Program.
