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.

The three main components of sunlight are ultraviolet radiation, visible light, and infrared radiation. Ultraviolet radiation can be further divided into UVA, UVB, and UVC rays.

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.
The common name for infrared radiation is heat radiation.
Natural background radiation
Secondary radiation refers to the radiation that is produced when primary radiation interacts with matter, leading to the emission of additional radiation. This secondary radiation can have different properties and energies compared to the original primary radiation.
