ABSTRACT:
Radioactive materials can be safely analyzed by an emission spectroscopic analyzer comprising an exciting device for exciting a radioactive material to be analyzed to emit light. The exciting device is enclosed in a radiation shielding wall. A detecting device detects the emitted light. The detecting device is located outside the radiation shielding wall. A light-transmitting device is provided between the exciting device and the detecting device such that the emitted light impinging on a first end of the light-transmitting device will be received at the detecting device as light having been transmitted through the light-transmitting device and emitted from a second end of the light-transmitting device. The light-transmitting device penetrates a hole made in the radiation shielding wall which has a sealing structure to prevent radiation leakage. The light-transmitting device penetrates the hole with a curvature. A lens system is attached to the second end of the light-transmitting device to permit visual observation of the emitted light therethrough. A fine adjustment device adjusts the position of the first end of the light-transmitting device in relation to the emitted light from the material to be analyzed.
