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.

Objet : Re: Radioactive 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.
