One fraction is usually given each day, five days a week for six to seven weeks
The solar radiation can be divided into many parts. The UV radiation part of it helps to form the ozone.
Radiation is energy emitted in the form of waves or particles. It can take many forms, such as light, heat, or X-rays. Radiation can be divided into ionizing radiation, which has enough energy to remove tightly bound electrons, and non-ionizing radiation, which lacks this capability.

Ultraviolet (UV) radiation from the sun is primarily responsible for sunburn. UV radiation is divided into three types: UVA, UVB, and UVC, with UVB being the most significant contributor to sunburn. It penetrates the skin and can damage the DNA in skin cells, leading to inflammation and the characteristic redness associated with sunburn. Prolonged exposure to UV radiation can also increase the risk of skin cancer.
The energy of one photon is given by its frequency X planck's constant Its frequency is given by the speed of light divided by the wavelength.
UV radiation is a type of electromagnetic radiation that comes from the sun and can also be emitted by artificial sources like tanning beds. It is divided into three categories: UVA, UVB, and UVC, with UVA and UVB reaching the Earth's surface and affecting human skin. Overexposure to UV radiation can cause skin damage, premature aging, and increase the risk of skin cancer.
Ultraviolet (UV) radiation spans a wide range of frequencies, typically from about 10^15 to 10^17 Hz. This range is further divided into UVA (315-400 nm), UVB (280-315 nm), and UVC (100-280 nm) wavelengths.
