Answer:
Electronic devices with the ability to emit potentially dangerous amounts of radiation are laser products.
Explanation:
Laser products —<em>light amplification by stimulated emission of radiation</em>— use radiation to concentrate light energy into a visible ray, capable of crossing space, and even vacuum, at long distances and remaining in a defined spectral range. Currently, many electronic devices use lasers, including some with medical applications.
Because the emission of laser light is potentially dangerous, they have been classified into classes, from 1 to 4, where class 1 is the most innocuous and class 4 is the most dangerous.
<em> The other options do not pose a radiation hazard, since </em><u><em>defibrillators</em></u><em>, </em><u><em>blenders</em></u><em> and </em><u><em>dialysis machines</em></u><em> use electrical energy and do not emit any radiation.</em>
the correct answer is 17.5 and underweight.
Have a nice day
