Abstract

PURPOSE: To measure the intensity of a feeble radiant ray exactly and easily by separating a signal of the radiant ray to be observed from the background signal and by modulating the intensity of the radiant ray as a function of time.
CONSTITUTION: The radiant ray source 2 to be observed is surrounded with the lead shield 3, the lead door 5 is installed in front of the aperture 4 and is reciprocated on right and left to give a proper time modulation to the radiant ray of the intensity S(t) emitted from the ray source 2, the modulated radiant ray of the intensity Sm(t) is led to the outside and is measured together with the background radiant ray of the intensity B(t) as the output of the detector 1, the data is processed by a microcomputer to separate the value of B(t) from the said output, and the desired intensity S(t) of the radiant ray is decided.
