Abstract:
Disclosed herein are a method and an apparatus to identify alpha-emitting radionuclides and to measure absolute alpha radioactivity using a low temperature detector. A 4&pgr; metallic absorber which encloses a radioactive material containing alpha-emitting radionuclides absorbs the total alpha decay energy in the form of thermal energy. The corresponding temperature changes are measured by a low temperature detector attached to the 4&pgr; absorber with high energy resolution. The identification of alpha-emitting radionuclides is declared by comparing the measured temperature signal with characteristic decay energy of radionuclides. The absolute amount of the radionuclides is determined by counting the number of the pulses for each of the identified nuclides.

The temperature sensor is mounted to the absorber. A magnetic flux detecting unit(30) is located at a lower part of the temperature sensor. A pickup loop coil of the magnetic flux detecting unit is mounted to the center point of the hole in the absorber.
Abstract:
A method for measuring absolute alpha radioactivity and identifying alpha-emitting-radionuclides using a low temperature detector and an apparatus using the same is provided to measure absolute alpha radioactivity accurately and identify alpha-emitting-radionuclides accurately by preventing alpha energy from being emitted outside. A method for measuring absolute alpha radioactivity and identifying alpha-emitting-radionuclides using a low temperature detector comprises following steps. An aurum foil formed sealing sample is prepared(S100). The aurum foil is set up at the low temperature detector(S200). The temperature signal according to the temperature change is obtained from the low temperature detector(S300). The amount of absolute radiation of radionuclide is measured from the temperature signal and the nuclide is determined(S400).
