Radon Mitigation >> How Do Radon Detectors Work

Enter the RPP Device Code(s) of the reading/analysis system you use to read the device listed in Section 3.1. If your reading/analysis system is self-contained or made up of a group of components listed under one brand/model/type, please use Checklist #2 to determine the five-digit device code associated with the entire reading/analysis package system How Do Radon Detectors Work and enter it on the first line. 

If, however, your reading/analysis system is made up of two or more components not designated by the manufacturer underone brand/model/type, please use Checklist #3 to provide one five-digit codes for each component related to your system. If you have more than four components, How Do Radon Detectors Work list only the four most critical components. 

For example, How Do Radon Detectors Work you could include multichannel analyzers (MCAs), MCA cards, single-channel analyzers (SCAs), amplifiers,gamma ray detectors, and photomultiplier tubes. Do not attempt to list computers, printers, stand-aloneair pumps, air filters, or filter holders.If you cannot find your system/components in the checklist, go to the end of the list and find the sectionmarked "OTHER (Devices not listed above)." 

Determine which of the two or three "other" designationsis most appropriate for your device, and How Do Radon Detectors Work enter that code (00997, 00998 or 00999) in the space provided.3.3: If you checked "other" in Section 3.2 because your system or component(s) were not on any checklist,EPA must determine whether your device can be tested in the RPP Program. 

You must submit a complete description of the system or component(s) with picture(s) for all such systems/components submitted along with your Application (see Section 7.3 of the Handbook for a full discussion of how How Do Radon Detectors Work devices may enter the RPP Program). Be sure to check the line to indicate that the required descriptionis attached. 

You must supply sample devices or pictures/photographs of your device to verify that thebrand/model/type of device submitted for the test is the same as described in the How Do Radon Detectors Work Application. Pleaseconsult the Device Checklist associated with your device to determine if a sample or photograph of yourdevice is required. 

Photographs may be a picture from the manufacturer's literature, and you may submit separate pictures for each component. Sample devices submitted with your Application will not be used for testing. When your Application has been found acceptable and How Do Radon Detectors Work your measurement test scheduled,you will receive either an appointment letter to schedule your performance test or a written request for detectors from the RQAC with specific instructions on how many devices to send for the test and when to send them.

Please enter the exposure range you recommend to consumers. Provide the minimum number of days How Do Radon Detectors Work and the maximum number of days you recommend.3.6: Please enter the maximum length of elapsed time in days you allow between the end of the detectorexposure and the analysis.NOTE: The information requested in items 3.5 and 3.6 is important for scheduling your performance test withcompatible devices in a radon chamber at an EPA laboratory. 

This information also must match the exposure instructions that you give to consumers. This How Do Radon Detectors Work information may be included in Program listings.4: Section 4 of this application should completed only by applicants who are applying with devices in the CR, CW, GB, GC, GS, GW, PB or SC measurement methods only (See Section 2 of this Part C Application).

This section requires you to consult Checklist No. 3 or No. 4 of the Application Device Checklists toprovide information about your device. EPA requires this device information to schedule your test alongwith compatible devices at its chamber facilities, How Do Radon Detectors Work and for listing purposes. If you have more than onesystem composed of different brands of equipment or components, please submit a separate Part C foreach system that you wish to enroll. 

Because it is common to use components interchangeably between systems, it may be useful for you to discuss your How Do Radon Detectors Work situation with the Radon Proficiency Program Information Service to determine whether separate Part C forms are appropriate for you. 

If your device is a self-contained system--that is, the device is sold as one specific brand/model/type, How Do Radon Detectors Work not including computer or printer--please use Checklist No. 4 to find the appropriate manufacturer's brand/model/type on the checklist and enter its corresponding five-digit RPP Device Code in the space provided. 

If, however, your reading/analysis system is not self-contained--that is, it is made up of two or more How Do Radon Detectors Work components not designated by the manufacturer under one brand/model/type--please useChecklist #3 to provide one five-digit codes for each component related to your system.If you have more than four components, list only the four most critical components. 

For example, youcould include counter/scalers, photomultiplier tubes (PMTs), scintillation disk holders, scintillation cells,and - particularly for the GB, GC, PB, and SC method - grab sampling units, multichannel analyzers(MCAs), MCA cards, How Do Radon Detectors Work single-channel analyzers (SCAs), amplifiers, and gamma ray detectors. 

Do not attempt to list computers, printers, stand-alone air pumps, air filters, or filter holders. If you cannot find your system/components in the checklist, How Do Radon Detectors Work go to the end of the list and find the section marked "OTHER (Devices not listed above)." Determine which of the two or three "other" designations is most appropriate for your device, and enter that code (00997, 00998 or 00999) in the space provided.

If you checked "other" in Section 4.1 because your system or component(s) were not on any checklist, EPA must determine whether your device can be tested in the RPP Program. You must submit a complete How Do Radon Detectors Work description of the system or component(s) with picture(s) for all such systems/components submitted along with your Application (see Section 7.3 of the Handbook for a full discussion of howdevices may enter the RPP Program). 

Be sure to check the line to indicate that the required descriptionis attached.4.3: You must supply sample devices or pictures/photographs of your device to verify that thebrand/model/type of device submitted for the test is the same as described in the How Do Radon Detectors Work Application. Pleaseconsult the Device Checklist associated with your device to determine if a sample or photograph of yourdevice is required.
