dose limit of 500 mrem/year applies. Users may not be required 

to wear a dosimeter. To establish the personnel monitoring 
requirements for your application, consult the conditions of 

your radioisotope license and the CNSC regulatory document 

R91: Monitoring and Dose Recording for the Individual

. 

Source Encapsulation 

The neutron (americium-241:beryllium in the Model 3440 and 

photon (cesium-137) source materials are welded inside 
stainless steel capsules. These sealed sources meet U.S. and 

international regulatory requirements for classification as 

“Special Form” radio

active material for purposes of 

transportation. The sealed sources are designed to prevent 
leakage of radioactive material under severe accident 

conditions. They are also designed to comply with applicable 
ANSI classification requirements for sealed sources used in 

portable gauges.  

Source Rod Inspection 

To ensure the integrity of the source rod, Troxler recommends 

that a qualified Troxler service person inspect the gauge and the 
source rod at least once every five years. This inspection 

includes checking for excessive wear, corrosion, or damage that 
could affect the safety of gauge operation. 
However, as a precaution if the gauge is ever damaged or 
dropped, ensure that the tip of the source rod is intact and 

undamaged (that is, ensure that the source is not missing) as 
described on page D-9.  
Contact the Troxler Radiation Safety Department for further 
advice.
