Abstract:
     This invention is a method for measuring microquantity container, especially for microquantity suction tube capacity. It uses the property that radioactive species 125 I and so on marking materials radio gamma, beta ray, to do relative counter measuring to the radioactive solution of 125 I in container through gamma ray counter detector under selected condition, then acquiring the counts per minute. The capacity can be converted according to the direct proportion betwen count ratio and capacity of radioactive solution under same condition, and then the capacity of container can be measured. Said invention has advantages of fast, simple, accurate and sensitive and so on. It can be widely used in scientific research, medical teaching and clinical check. It also can be used for checking the products quality for standard measuring dept. and factorys of producing microquanty container.
