Re: Radioactive Tracers

[NSSIHOU@AOL.COM]

While not aware of any prohibitions on the use of radiotracers for subsurface 

oil well tracing, I am not surprised. With the current phobia concerning all 

things radioactive and terrorist concerns, it is only a matter of time before 

radioactive materials and sources become more limited in usage. With the 

availability of stable isotopes and analysis, it was only a matter of time before 

radiotracers lost favor. 



As a primary vendor and disposer of oil well logging sources, we are noting 

significant interest in other than nuclear technologies for oil formation 

evaluation. In addition, there are currently many ongoing investigations around the 

world concerning lost or stolen radioactive materials and sources associated 

with oil related applications. 



Companies involved with handling radioactive materials and sources recognize 

the significant legal liability they are exposed to using such materials in 

foreign applications and are returning any uneeded source to the U.S. for reuse 

or disposal.
