Quantum pendants: Assessing exposure dose and concurrent radiation hazard

Scalar energy pendants are widely accessible, and their sellers claim that they enhance the body 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 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.
