In News: Recently, it has been decided that Ultraviolet-C (UV-C) air duct disinfection systems would be installed in Parliament for mitigation of Covid-19.
Statement 1 is correct: Ultraviolet Light is a type of light or radiation naturally emitted by the Sun and covers a wavelength range of 100-400 nm (human visible light ranges from 380-700 nm).
Statement 2 is not correct: UV-A and UV-B rays from the Sun are transmitted through the atmosphere and all UV-C is filtered by the ozone layer.
Statement 3 is not correct: UV-B (wavelength 280-315 nm) can only reach the outer layer of skin or epidermis and can cause sunburns and are also associated with skin cancer. UV-A (315-400 nm) can penetrate the middle layer of skin or the dermis and can cause aging of skin cells and indirect damage to cells’ DNA. UV-C (100-280 nm) radiation from man-made sources has been known to cause skin bums and eye injuries.

3. UV radiation can cause damage to the skin, including sunburn and skin cancer.
All of the statements are true. UV radiation is naturally emitted and covers the wavelength range of 100-400 nm. UV-B and UV-C radiations can reach the Earth's surface, although most of the UV-C radiation is absorbed by the ozone layer. UV radiation is known to cause damage to the skin, including sunburn and an increased risk of skin cancer.
