RE: Radioactive Tracers



Hi radsafers,

 

In France there is no law forbidding the use of radioactive tracers. But it

is more and more difficult to have the legal authorization from the Nuclear

Safety Authority to use them.

The requests for the use of the tracers have to be well justified and when

other tracers can be used (chemical or else), the authorizations are not

granted, even if the detection level is several orders of magnitude lower

than for radioactive tracers.

And when you get this authorization from the national authority, some local

sanitary authorities refuses to let you use these tracers.

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.
