Answer:
Electronic devices with the ability to emit potentially dangerous amounts of radiation are laser products.
Step-by-step explanation:
Laser products —light amplification by stimulated emission of radiation— 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.
The other options do not pose a radiation hazard, since defibrillators, blenders and dialysis machines use electrical energy and do not emit any radiation.
