Many people are concerned that luminous alarms can cause radiation hazards to the human body, so does luminous alarms have radiation? Night light alarm clocks are divided into two types: light storage type night light alarm clocks and self luminous type night light alarm clocks. Among them, light storage type night light alarm clocks are harmless, while self luminous type night light alarm clocks need to judge whether they are harmful based on the night light material used:

1. The luminous alarm clock using laser compound luminous powder must have radiation, and the radiation will be very large, but this type of alarm clock is no longer produced.

2. Although noctilucent materials made from tritium have some radiation, tritium is pure β Particle emitters with a range of only 0.4 centimeters. And the penetration is very weak, basically unable to penetrate the mirror of the alarm clock; And the amount of nighttime light alarm clocks made with tritium is generally very small, and there is basically no harm.

3. The new type of luminous material, named Luminova, was invented in the mid-1990s. It is an environmentally friendly and non radiative material, and most of the luminous alarm clocks produced today are made of this material without any harm.
