Abstract: A radiation detection device includes a driving device used to generate an output signal according to a source signal. The source signal includes a rising duration corresponding to a first pulse and a second pulse of the output signal. The first pulse has a pulse width greater than the second pulse.

Abstract: The heat dissipating casing structure contains a metallic casing, a metallic heat conducting block, and a heat conducting paste. The heat conducting block is positioned inside and attached to the casing. The heat conducting paste is disposed on the heat conducting block. When a main board is positioned inside the casing, the heat conducting paste is behind a heat source of the main board and is attached to the main board. The heat produced by the heat source therefore could be conducted to the casing through the heat conducting paste and the heat conducting block. By the large exposure area of the casing to the outside atmosphere, the heat could be easily dissipated, even after power is turned off.
