Visible light and infrared radiation are two types of solar radiation that are not harmful to human beings. They are part of the electromagnetic spectrum and are essential for processes such as photosynthesis and vision.
It is. It is called sun-burn. A good example of too much of a good thing.
UV-B radiations are very harmful. They can cause various fatal diseases in human beings.
they are not harmful to the environment
Radiation is lethal to Humans, So no.
Chlorofluorocarbons (CFCs) are harmful to the environment primarily because they deplete the ozone layer, which protects living beings from harmful ultraviolet (UV) radiation. When CFCs are released into the atmosphere, they eventually break down and release chlorine atoms, which catalyze the destruction of ozone molecules. Increased UV radiation due to ozone depletion can lead to higher rates of skin cancer, cataracts, and weakened immune systems in humans, as well as detrimental effects on wildlife and ecosystems. Additionally, CFCs are potent greenhouse gases, contributing to climate change.
Yes
microsporium is a terrible fungi that is harmful to human beings
Yes, guitar amplifiers emit electromagnetic radiation as a byproduct of converting electrical signals into sound waves. This radiation is generally considered low-level and not harmful to human health.
Lead
No, Cobalamin (B12) is a vitamin necessary to the human body.
Ozone layer is very important for human beings. It protects us from the harmful UV radiations of the sun.
