Already done my man, you need a lead pig, a cesium source, 135 0r 137 and a receptor. Anyhow it's how they X-ray airplane wings for cracks. Radiation source is carried in a lead pig with a long cable, huge sheets of film are placed on the wing, the end of the lead pig line is positioned in such a way that it will pass radiation through the wing to the film receptor. The lead pig has a crank, when you turn it a radioactive pellet comes out of the lead protectant and travels down the cable into position. The wing is now being irradiated, time is dependant on distance and thickness, a tech comes back, and winds the pellet back into the pig, develops the films and viola, there's your image of a metal component. I'm sure today the method may include using no film, replaced with TFT (thin film transistor) DR plates, lead pig I'll bet is the same.
