Instrument Check Sources

These single or mixed radionuclide sources which have been developed to check the correct functioning of radiation measurement equipment such as surface contamination monitors, survey dosimeters and personal dosimeters. Stainless steel encapsulated sources are also available for instrument checking and oil well logging devices. 

Mixed Nuclide check source

Part number: QCRB1282

Part number: QCRB1282 These sources emit alpha-, beta- and gamma-radiation for checking the operation of surface contamination monitors and survey dosimeters.  The source is constructed from 3 active components (drawing: VZ-1444). Am-241 is incorporated in the surface of an anodized...

Instrument Check Source Gamma/Beta Cs-137

Part number: 300829

Part number: 300829 A sealed check source for daily function test of your dose rate instrument and/or beta probe. Expose your instrument at a fixed distance and readout the dose rate to verify that the measure...

Instrument Check Source Alpha Am-241

Part number: 300866

Part number: 300866 A check source for daily function test of your alpha instrument. The americium activity is sealed with a 50 µg/cm² gold layer. Activty and isotope is engraved in the aluminium rod. A desktop stand lead...

Set with Alpha, Beta, Gamma Check Sources

Part number: 300366

Part number: 300366 A cost-effecive set containing 2 rods, one with Cs-137 and one with Am-241. The set includes a lead shield. These sealed sources are uncalibrated and should be used for instrument check, eduacation and...

Part number: CDR829902, CDRB8151

Part number: CDR829902, CDRB8151 All radiation detection instruments should be checked daily to ensure that they are working correctly. The sources in this section from Isotrak, offer a cost-effective and convenient method to perform functionality checks. These sources are uncalibrated and can...

Wide area sources - Planchet, Ring and Rectangular sources Isotrak (EU)

The wide area standards are designed for the calibration wide area counters and low level counters. Each source come with a certificate stateing the emission, activity, traceabillity and uncertainty. The Isotrak sources from Nuclitec...

Wide area sources - Planchet, Ring and Rectangular source from Analytics (US)

These standards are used for the calibration of alpha, beta and wide area counters. All sources are NIST traceable based on output or contained activity. NIST certification on contained activity is not available on some...
