Semi-quantitative spectrometer, issues related to human radiation

A handheld X-ray fluorescence spectrometer generates X-rays using an internal high-voltage generator to excite the electrons on the surface of the object being analyzed; as these electrons make transitions, energy is released, resulting in the characteristic spectral lines of various elements. When designing handheld X-ray fluorescence spectrometers, safety is the top priority. The radiation from handheld X-ray fluorescence spectrometers is virtually negligible, and as long as they are used properly, they do not cause harm to the human body. Nevertheless, we must still pay attention to safety when using the instruments, in order to ensure the personal safety of the operator and those around them. Some people say that as long as the testing window is not directed at the human body while the instrument is in use, the level of radiation is very low, so there is no need to worry. I think the primary concern for instrument manufacturers should be safety; therefore, it’s better to choose a reputable brand when making a purchase. As long as the instructions are followed carefully, there should be no major problems.
