Abstract Objective To analyzed the types of radionuclides in the body and accurately and measure the activity of radionuclides by whole body counter.Methods Considering the correction of equivalent of muscle wall thickness and tissue thickness, the launched single and mutli-energy gamma-ray radionuclides was applied to calibrate the whole body counter which includes energy and efficiency calibration.Results The method of direct measurement radionuclides' activity is established, which was tested by experiment and provides an effective method to accurately obtain the activity in the human body;Conclusion The method of direct measurement radionuclides in human body is feasible.
