I don't know how strong the radiation is from the electrical devices you mentioned, but the water is generally drinkable. Generally, the frequency of electromagnetic radiation from household appliances is relatively low, and the direct effect on the human body in water is generally drinkable. in the short term should be harmless or very low. The impact, not to mention the water used for absorption.
Any object above absolute zero will emit electromagnetic radiation from extremely low frequency to extremely high frequency. electromagnetic radiation, there is a range between the two. There is also electromagnetic radiation such as radio waves, microwaves, infrared rays, visible light and ultraviolet light. Personally, it is recommended that objects that have been exposed to high temperatures (including ultraviolet light) Electromagnetic radiatione high frequency should not be eaten/drank for a long time!
Ultraviolet light is useful for disinfection and sterilization, but it should be left on for a while before eating/drinking. , because ultraviolet light irradiation will produce ozone, and excess ozone is very harmful to the human body. Everything will be fine after a while.
