Radon and Thoron Measurements
PTC works with Pylon Electronics to supply a complete range of monitors, detectors, accessories and radioactive sources for radon, thoron, and their progeny detection and measurement.

Monitor

AB-5/AB-5R Portable Radiation Monitors

The AB-5 series of portable radiation monitors are Pylon's most popular model of monitors. This monitor series uses proven photomultiplier tube (PMT) technology to detect photons generated by scintillation type detectors. The monitors are portable and easy to use in a wide variety of applications. A wide variety of detectors and accessories are available for the AB-5 series of monitors.

The AB-5R is an AB-5 that is incorporated in a more rugged chassis. Due to the wide range of detectors designed for these monitors, the monitors are sold without a detector. This allows the User to choose the required detector for their application.


AB-4/AB-4A Portable Radiation Monitors

The AB-4 series of portable radiation monitors are another popular model of monitors. This monitor series also uses proven photomultiplier tube (PMT) technology to detect photons generated by the supplied Lucas type passive scintillation cell detector. The monitors are also portable and easy to use. They are specifically designed to passively detect and measure radon.

The AB-4A is an AB-4 complete with a factory installed internal printer and temperature, relative humidity, and barometric pressure sensor module. The factory installed internal printer and temperature, relative humidity, and barometric pressure sensor module are also each sold separately.


WLx Working Level Monitor

The WLx is a popular radon and thoron working level measurement monitor. This monitor used proven, integrated solid state detector technology to detect alpha particles from radon and thoron progeny decay. The built in multi-channel analyzer circuitry and firmware allows the monitor to calculate radon, thoron, and their progeny in working levels (WL). The WLx is portable and easy to use.


CRM-1 Active Radiation Monitor

The CRM-1 is a popular industrial radon monitor that is used to actively monitor radon in process gases. The CRM-1 also uses proven photomultiplier tube (PMT) technology to detect photons generated by the supplied Lucas type active scintillation cell detector. This monitor incorporates a lockable chassis that is designed for inclement weather conditions. It is designed to be mounted on a surface such as a wall. It is easy to use.


CRM-2 Passive Radiation Monitor

The CRM-2 is a popular industrial radon monitor that is used to passively monitor radon over an area. The CRM-2 also uses proven photomultiplier tube (PMT) technology to detect photons generated by the supplied Lucas type passive scintillation cell detector. This monitor also incorporates a lockable chassis that is designed for inclement weather conditions. It is also designed to be mounted on a surface such as a wall. It is also easy to use.


Detectors

CPRD / CPC / 200P Passive Cells

Pylon's Instrument Manufacturing Division passive cells are Lucas type scintillation cells. Passive cells are primarily used for area monitoring in continuous mode. The atmosphere that contains radon and / or thoron gas passively diffuses into the cell.

Pylon also offers non standard versions of these cells including variants that are designed to detect high radon and thoron activity levels. (e.g., 20,000,000 pCi.)


110A / 300A / 200A Active Cells

Pylon's Instrument Manufacturing Division active cells are Lucas type scintillation cells. Active cells are used for grab sampling, continuous monitoring, sniffing, etc. The atmosphere or sample that contains radon and / or thoron gas is actively placed into the cell.

Pylon also offers non standard versions of these cells including variants that are designed to detect high radon and thoron activity levels. (e.g., 20,000,000 pCi.)


TEL Environmental Level Detector

Pylon's Instrument Manufacturing Division offers the model TEL - Trace Environmental Level detector that detects trace levels of radon. This detector is normally used for monitoring outdoor or very low level environments. It may be used for grab sampling or continuous monitoring.

This detector is designed for use with the Pylon model AB-5 series of monitors and requires an external photomultiplier tube (Ext PMT) [Both sold separately] to complete the minimum required system.


WT-A / WT-B / WT-AB Wipe Test Adapter Detectors

Pylon's Instrument Manufacturing Division offers a series of wipe test adapter detectors. These detectors allow the User to measure alpha and / or beta radiation from wipes or swipes with the Pylon model AB-5 series of monitors [Sold separately].


SA / SB / SAB Surface Detectors

Pylon's Instrument Manufacturing Division offers a series of surface detectors. These detectors allow the User to measure alpha and / or beta radiation over a surface to find "hot spots" with the Pylon model AB-5 series of monitors.

These detectors are designed for use with the Pylon model AB-5 series of monitors and requires an external photomultiplier tube (Ext PMT) [Both sold separately] to complete the minimum required system.


AEP-47 / BEP-47 Working Level Detectors

Pylon's Instrument Manufacturing Division offers 2 working level detectors that allow the User to measure alpha or beta radiation using the Pylon model AB-5 series of monitors [Sold separately]. The working level (WL) can be calculated from the results.


503 Filter Detectors

Pylon's Instrument Manufacturing Division offers the model 503 detector. This detector allows the User to measure alpha radiation on filters with the Pylon model AB-5 series of monitors [Sold separately].


GB Gamma / Beta Detector

Pylon's Instrument Manufacturing Division offers the model GB - Gamma / Beta Probe that detects gamma and beta radiation. It may be used for comparative measurements or continuous monitoring.

This detector is designed for use with the Pylon model AB-5 series of monitors and requires an external photomultiplier tube (Ext PMT) [Both sold separately] to complete the minimum required system.


Radioactive Sources

3150A / 4250A

The 3150A and 4250A are two sealed, passive radon check sources that are designed to assist with the operating point determination of Pylon and other monitors. These check sources use the same geometry as the Pylon Lucas type scintillation cell detectors.


WLx-AM / AM-241

The AM-241 is a passive Americium 241 disk alpha source. The WLx-AM is the AM-241 disk source mounted in a holder that is designed to mount to the WLx. The WLx-AM is used to verify the operation of the WLx.


RN-150

The RN-150 is an active radon gas source that can dispense precise quantities of radon gas. The design allows for multiple samples to be obtained from the unit. This source may be used to provide radon gas to sealed detectors to allow for the calibration and verification of various monitors.


RN-190 / TH-190

The RN-190 and TH-190 are passive radon and thoron daughter sources respectively. Each offers geometric and spectroscopic characteristics that are virtually identical to a filtered air sample. The exposed filters obtained from these sources allow the for calibration and verification of various monitors.


RGS

The RGS series of sources are sealed gamma sources that use radium as the source material. This general purpose source may be used for the calibration and alignment of gamma spectroscopy systems.


2000A

The 2000A is a small, general purpose, passive radon source. It may be used to provide radon gas for sealed enclosures.


RN-1025 / TH-1025/ RNC

The 1025 and RNC are general purpose, flow through sources. The RN-1025 and RNC are radon sources while the TH-1025 is a thoron source. The 1025 sources are available in a wide variety and range of activities.
