Abstract

Occupational health and safety: measurement and analysis of the electromagnetic radiation produced by radiofrequency devices for rejuvenation Wei S, Zhou C, Huang L. Occupational health and safety: measurement and analysis of the electromagnetic radiation produced by radiofrequency devices for rejuvenation. Lasers Med Sci. 2022 Dec 27;38(1):25. doi: 10.1007/s10103-022-03669-y. Abstract With the ongoing development of cosmetic technology, many different types of radiofrequency (RF) devices are widely used for face and body rejuvenation. These, like many other high-power devices, may emit excessive electromagnetic radiation into the surrounding environment. Long-term exposure to this environment can lead to poor health outcomes; therefore, it is important to measure and analyze the electromagnetic radiation levels for the health and safety of therapists. A handheld electronic electromagnetic radiation measuring instrument was used to measure the electric and magnetic field strengths. All results were analyzed using the R software (R Core Team, 2021-02-15). We found that the monopolar and unipolar RF devices that we measured from, in this study, could produce large amounts of electromagnetic radiofrequency emissions during operation, whereas the microneedle RF (bipolar RF) device emitted relatively lower amounts (P < 0.01). The strength of electromagnetic radiation is related to power and distance; it increases with power and decreases with distance. This study proved that certain RF devices for rejuvenation could cause severe electromagnetic radiofrequency pollution. The occupational health and safety of therapists require more attention, and effective protective measures need to be taken immediately. pubmed.ncbi.nlm.nih.gov

Main findings

Using a handheld electromagnetic radiation measuring instrument, the authors report that monopolar and unipolar RF rejuvenation devices produced larger RF emissions during operation than a microneedle (bipolar) RF device (P < 0.01). Measured electromagnetic radiation strength increased with power and decreased with distance; the authors conclude certain RF rejuvenation devices could cause severe RF pollution in the surrounding environment.
