The geiger counter used by Sean Connery in the film Dr No is a real instrument, it's the Thorn EMI Portable Contamination Monitor No. 1, or PCM1, which used 12 D cell 1.5 volt batteries. In the film, it is coupled to geiger muller probe type BP3. However, the box is designed principally for the scintillation dual phosphor probe DP2, which discriminates between alpha and beta particles to produce beeps for alphas and clicks for betas, using a pulse height discriminator circuit (typical 5 MeV alpha particles produce a 10 times brighter flash when hitting zinc sulphide phosphor, than typical 0.5 MeV beta particles when they hit a plastic phosphor). The user handbook explains all this in greater detail with pictures, and it is online in PDF format.

thanks.
I think that the next icon will give enough clue what is this all about.

It has a nice 3d look but the buttons on the right side needs some work (black one's).
