no it can't
Sand is not good to eat. Small amounts won't hurt.
Yes. studies have shown that small amounts of micro wavelengths are in human urine.
Background radiation - is the 'natural' radiation of the Earth. There are radioactive ores naturally present in the ground that give off small amounts of radiation. This is detectable by instruments, but is of no consequence to humans or animals.
Yes, the sun rays contain dangerous amounts of Ultra-violet radiation that can hurt your eyes and your skin.
Electromagnetic radiation is made of energy. Very small amount of energy for radio waves or large amounts of energy for gamma rays. Visible light is electromagnetic radiation.
Small amounts of radiation from damaged nuclear plants in Japan have already reached California but they pose no health threats at all. Any radiation that reaches California from Japan is well dissipated by the time it gets there.
The answer depends on what type of radiation and how much. Small amounts of infra-red radiation will make you feel warm, large amounts will burn you. Visible light has little effect. Small amounts of some ultra violet radiation will help you synthesise vitamin D and also give you a tan. Large amounts will cause sun burn and is likely to lead to skin melanomas and cancers. Absorbing more powerful radiation - such as gamma waves - is much more likely to cause cancers and lead to genetic mutations.
Yes, some light bulbs, such as fluorescent and LED bulbs, can emit small amounts of ultraviolet (UV) radiation. UV radiation is not visible to the human eye but can have potential health risks if exposure is prolonged.
Potting soil is a lighter mix than garden soil. Small amounts won't hurt.
well, it can be. small amounts won't hurt, but in large amounts, as with any food, it will make them unwell, and in some cases, cause colic. so, you can feed them a little bit
A planet is a celestial body that does not emit substantial amounts of radiation and that circulates around a star (which DOES emit substantial amounts of radiation)
If the patient continues to drink while doing radiation therapy his throat will hurt. Radiation already will burn the esophagus, and when you combine that with alcohol, it will hurt. If it hurts, the patient wont go in for treatments, too many inconsistencies with radiation treatment and it will be ineffective.
