Abstract

There are products available on the online market that are claim to contain unique 'energies' that can improve health and wellness by eliminating toxins and pains and energising food and drinking water. We investigated these products by alpha and gamma spectrometry, and the analysis showed that they contained a few to hundreds of kilobecquerels per kilogram of naturally occurring radionuclides from the 232Th and 238U series. The committed effective dose for an adult drinking water that had been in contact with these products just once was estimated to 12 nSv. Considering a worst-case scenario for the workers inhaling the radioactive substance, 1 d of work would result in an effective dose of 0.39 mSv. The product descriptions do not mention the radionuclide content, and concerns are raised for the consumers and workers exposed to these products with no knowledge of the radioactive content.

摘要

市面上有一些声称含有独特“能量”的产品，据称可以通过消除毒素和疼痛、为食物和饮用水提供能量来改善健康和活力。我们通过阿尔法和伽马谱仪对这些产品进行了调查，分析表明它们每公斤含有几到几百千贝克勒尔的来自 232Th 和 238U 系列的天然放射性核素。一个成年人一旦饮用了与这些产品接触过的水，其估计的年摄入量有效剂量为 12 纳希沃特。对于吸入放射性物质的工人来说，最坏的情况下，一天的工作就会导致 0.39 毫希沃特的有效剂量。产品说明没有提到放射性核素含量，而对于接触这些产品但不知道放射性含量的消费者和工人，人们表示担忧。
