Abstract

PURPOSE:To perform safely the measurement of a radioactive substance in high accuracy and to facilitate the remote maintenance of calibration work etc., by utilizing a light guide. CONSTITUTION:Light emitted from a light source 15 passes through a spectorscope 14 and is made into a signal monochrome, and is made incident to an absorbance measuring cell 11 through a light guide 13a of the light incidence side. Then, the quantity of the light is felt by absorption and said light arrives at a photodetector 14 through a light guide 13b of the light emitting side. At this time, a liquid in the cell 11 is a diluted sample liquid 5 and is flowed at a fixed running speed by a constant flow pump 8 and an increase of absorbing quantity of light, that is, the concentration of a hydrogen ion is found by measuring a decrease of transmitting quantity of pulse-like light at the operating time by using the transmitting quantity of the light at the non-operating time of an adding device 10 of pH indicator as a base line. In this manner, in case of treating a radioactive substance as a sample, maintenance work, etc. are carried out safely and easily by installing the part of the cell 11 inside a shielding body 17 such as a lead cell, a globe box etc. and installing the light source 15 etc. outside the cell 11.
