ABSTRACT:
The present invention relates to the method and equipment for inspecting nuclear experimental locales, and particularly relates to the method and system for separating and measuring37Ar quickly. The method of the invention comprises the steps of sampling, eliminating impurities, separating, purifying, measuring the sum of Ar, collecting Ar, measuring the activity of37Ar, etc. The control unit in the system of the invention connects respectively to a sampling unit, a separating-purifying unit, and a radioactivity measuring unit which are connected in turn, and a computer and the software of the control unit are in charge of the automatic operation, measurement and data-collection of the whole system. The method and system for quickly separating and measuring37Ar of the patent can meet the requirements of locales inspection for Comprehensive Test Ban Treaty (CTBT), the sensitivity of measuring37Ar is high, so do the production and purity of Ar. The system can also be operated on vehicle, which is flexible and has good work efficiency.
