This caught my eye too. I wouldn't have expected dosimeters to detect <br>
anything from EMF radiation (except, maybe, gamma rays).<br></blockquote><div><br></div><div>Exactly ... <br></div><div><br></div><div>For background ... <br></div><div><br></div><div>Gamma rays (and X-rays and UV) are just photons, like the light we see with our eyes, <br></div><div>or infrared we feel as warmth, or radio waves around use form FM, TV, cell or WiFi. <br></div><div><br></div><div>Here is a visual of the <a href="https://www.nist.gov/image/emspectrumpropertiesedited-02png">electromagnetic spectrum</a>.
