【Abstract】 The contamination on surface and in air by tritium targcts used for accelerator,and the release rate of tritium from the target into air have been determined.Experimental results show that contamination at the area near the tritium target is very serious.However,the contamination caused by tritium targets may greatly be reduced as long as the tritium target are stored in a vacuum desiccator.更多还原
