There are around 1000 Radioisotope Thermoelectric Generators, or RTGs, in Russia, most of which are used as power sources for lighthouses and navigation beacons. All Russian RTGs have long exhausted their designed service periods and are in dire need of dismantlement. The urgency of this task is underscored by three recent incidents with these potentially dangerous radioactivity sources in 2003�one on the shore of the Baltic Sea, in March, and the most recent two, in the Kola Bay, in November.

In 1992, Bellona released a working paper on 132 lighthouses scattered along the shoreline of Northwest Russia, which are all powered by RTGs. One of them, in fact, is located just a few dozen metres from the Norwegian border.1

Bellona has warned that radioactive incidents involving these RTGs are possible, both because of the decrepit state of these old lighthouses and because the of premeditated theft of radioactive strontium 90, or 90Sr, that is contained in RTGs. Russia�s RTGs that have been used beyond their operational limits have been waiting to be sent to a repository for decades. At best, however, the nuclear installations presenting the most critical case of sitting on the decommissioning waiting list are stored at sites that are neither appropriate for this task nor meet any safety or security standards. At worst, they become prey of �non-ferrous metal hunters,� who crave to make a quick buck on RTGs, disregarding the risk of radioactive contamination to both themselves and other people.

Most Russian RTGs are completely unguarded against potential thieves or intruders, lacking such minimal security measures as fences or even signs warning of radioactive dangers. Nuclear inspectors visit these sites as seldom as once in six months, and some RTGs have not been checked for more than a decade.

But the biggest danger coming from these unprotected RTGs is their availability to terrorists, who can use the radioactive materials contained in them to make so-called "dirty bombs" bombs that are triggered by standard explosives, but disperse radioactivity. The damage from such an explosion could surpass by many times that from a conventional bomb, with the ground zero area potentially, dozens of kilometres remaining radioactively contaminated for years to come.

Here is where the great risk to human health and life exists. I am not a conspiracy theory person but to put such devices out in the open with little or no safe guards is stupid. All it will take is some half-wit dumb ass to cause grave harm to human life any place they want.
There are 100's of these devices in use. Some are/were in use in Alaska by our own government for use at radar/detection sites.
