ABSTRACT:
A method of quantitative measurement of a very small amount of low-energy beta radioactivity in a biological sample, a process for preparing samples and a device therefore, which require no large-scaled equipment and no labor for sample preparation, measurement, correction of the measured values and treatment of waste solution after measurement. The method comprises: forming a solid, liquid or liquefied biological sample containing a radioactive substance so as to have a substantially uniform and predetermined thickness; freezing or solidifying the sample and measuring the radioactivity thereof.
