What are UV radiations?

UV radiation is a kind of non-ionizing radiation released by the sun as well as artificial sources like tanning beds.
While it has certain advantages for individuals, like as the production of Vitamin D, it may also be harmful to their health.
The sun is our natural source of UV radiation.

Harmful effect of UV rays

UVB rays have a minor advantage over UVA rays in terms of energy.
They are the principal rays that cause sunburns because they may directly damage the DNA in skin cells.
They are also suspected to be the cause of the majority of skin malignancies.
UVC rays have a higher energy level than other UV rays.
Sunburns, skin cancer, ageing, and snow blindness (a sunburn to the cornea that causes a temporary loss of vision) are all caused by UVB rays, which can also reduce your body's capacity to fight sickness.

Prevention of UV radiation

Shade your face, head, ears, and neck with a wide-brimmed hat.

Wraparound sunglasses that prevent UVA and UVB rays are recommended.

For UVA and UVB protection, use sunscreen with a sun protection factor SPF of 15 or greater i.e. 30.

Indoor tanning should be avoided.

Hence, the correct options are A,B,B,B,B,C,A,D,A,B,A,C respectively.
