I am researching methods to detect the position of radioactive materials (emitting gamma and beta particles), and would like to know what current methods are used to do this.
What type of sensors are used, and how do they process the information to detect the position of a radioactive material in 3d space?
Are there any limitations/difficulties with these methods? e.g computationally expensive, inaccurate, only works for one type of element etc.
I'm developing my own method to detect the position of radioactive material in 3d space, and I'd like to know what the current standard method for doing this is so I can research and compare the methods.
My method involves liquid scintillation counters and a neural network.
The material will be highly radioactive. e.g 100g of uranium. It is limited to (4x14x6)m area, and could be buried in a solid, surrounded by air, inside a container. However I am assuming that the matter surrounding the radioactive material is uniformly distributed with constant density.
