[ RadSafe ] Proliferation: the case of radioactive isotopes toIran

[Robert Atkinson]

It is interesting that this thread and the original article concentrated
on the use of the moisture density gauges in RDD's. 
There is another proliferation issue, the use of Am-Be as a neutron
source in the trigger of a conventional nuclear device. This and its use
as a reflector are the reasons that Beryllium is controlled as a
"dual-use" product.

Why are we doing this again?  Iran has scores of much larger sources in
use and many more retired sources. What's the issue?

This is what I wrote before -

Iran is a huge oil producer, and the nature of petroleum exploration /
development entails geophysical borehole logging - always with
gamma-gamma density and neutron porosity tools with sources comparable
to the IAEA Category 2 and 3. I'm sure that they have scores of sources
in the Iranian petroleum industry currently in use, and have retired
scores more. Not to mention large teletherapy sources for cancer
treatment or food preparation / sterilization.

Proliferation: the case of radioactive isotopes to Iran
       
 On 22 July, a truck containing 10 lead-lined boxes was intercepted at
the Bulgarian-Romanian border, after Bulgarian scanning detectors
measured radiation 200 times the normal background radiation. The
consignment, destined for Iran, was discovered by the Bulgarian Nuclear
Regulatory Agency (NPA) to contain soil-measuring devices incorporating
the radioisotopes cesium-137 and americium-beryllium. In the light of
the continuing controversy over Iran's record of nondisclosure about its
nuclear activities, questions arise as to the intended purpose of such a
consignment.
