Scalar energy pendants are widely accessible, and their sellers claim that they enhance the body's energy flow, restore energy levels, and help maintain health and well-being. This study conducted radiological assessments of six pendants coded as QP1–QP6, including measurement of equivalent dose rates using a portable dose rate meter and software, assessment of the surface contamination, and a wipe test for removable contamination. Skin dose measurements were conducted using thermoluminescence dosimetry, and high-resolution gamma-ray spectrometry analysis was conducted. The committed effective dose (CED) of radionuclides ingested was also calculated based on the International Commission on Radiological Protection's Publication 119 Compendium of Dose Coefficients, and the activity concentrations from the pendants were compared with the International Atomic Energy Agency (IAEA) SSG-36 report. Sample QP1 demonstrated a maximum external effective dose of 0.3 μSv/h and a contamination level of 91.0 counts per second of contact. The wipe test for removable contamination indicated no reading above the background level for any of the six pendants. Gamma spectroscopy revealed that Uranium-238 and Thorium-232 activity were highest in QP1 at 7.5 and 52.4 Bq/g and lowest in QP2 at 2.3 and 16.5 Bq/g, respectively. The identified specific activities were above the IAEA exemption limit of 1 Bq/g for naturally occurring Uranium-238 and Thorium-232. The CED calculations indicated that ingestion of these samples contributes less than 1.0 mSv/year, which can be viewed as negligible. However, the pendants showed doses several times higher than the IAEA limit of 10 μSv/year for consumer products. In conclusion, scalar energy pendants provide an unnecessary radiation dose to wearers, and regularly wearing these products may be associated with chronic receipt of low-dose-rate radiation. This study recommend member of the public to be aware of such product and been banned from circulation to the public.

标量能量吊坠随处可见，其卖家声称它们可以增强身体的能量流动，恢复能量水平，并有助于维持健康和福祉。本研究对编码为 QP1-QP6 的 6 个吊坠进行了放射学评估，包括使用便携式剂量率计和软件测量等效剂量率、表面污染评估以及可去除污染物的擦拭测试。使用热释光剂量测定法进行皮肤剂量测量，并进行高分辨率伽马射线光谱分析。摄入放射性核素的承诺有效剂量（CED）也是根据国际辐射防护委员会第119号出版物剂量系数纲要计算的，并将吊坠的活度浓度与国际原子能机构（IAEA）SSG-36报告进行比较。样品 QP1 的最大外部有效剂量为 0.3 μSv/h，污染水平为每秒接触计数 91.0。可去除污染的擦拭测试表明，六个吊坠中任何一个的读数都没有高于背景水平。伽马能谱显示，铀 238 和钍 232 活性在 QP1 中最高，分别为 7.5 和 52.4 Bq/g，在 QP2 中最低，分别为 2.3 和 16.5 Bq/g。已确定的具体活动高于原子能机构对天然存在的铀 238 和钍 232 的 1 Bq/g 豁免限值。 CED 计算表明，摄入这些样本的贡献小于 1.0 mSv/年，可以忽略不计。然而，吊坠显示的剂量比 IAEA 消费品限值 10 μSv/年高出几倍。总之，标量能量吊坠为佩戴者提供了不必要的辐射剂量，经常佩戴这些产品可能与长期接受低剂量率辐射有关。本研究建议公众了解此类产品并禁止向公众流通。
