Let me break down the bull*h&t listed in the article you site on missing rad materials; "The gauge, used to measure how well the dirt is packed under roadways and pipelines, contains harmful radioactive material." Harmful- How is it harmful in it's current state? It isn't of course. All 'radioactive material' is labelled as 'harmful/cancer causing/life threatening' if anyone but the licensed user has posession..if you listen to the mainstream press idiots. If I were going to mess with dirty bombs, ripping off a 'SEALED SOURCE like a Troxler guage sure wouldn't be worth the time. But, they want you to believe the average use product is going to misteriously transform into a 'killing' product. What crap! "Similar material can be found in a broad array of equipment, including cancer radiation therapy machines, irradiation devices used to sterilize food, gamma ray cameras used in pipeline construction, and even unlikely devices such as a highway "exit" sign illuminated by radioactive material." More BS. Trying to remove a sealed source from any of these devices isn't worth the effort of even the most stupid terrorist . Too time consuming and easy to get caught. And, there haven't been tritium filled 'exit' signs manufactured anywhere in over 30 years. We certainly don't use them as 'highway' exit signs so I have no clue where the reporter drug that bit of ancient history up from. Luminescent paints are the 'trip' now..not H-3 signage. It's all part of the scare and be scared tactic. Sensational, right?
