What is radiation
What is radiation?
Radiation is a natural part of our living environment. There are two kinds of radiation – ionising and non-ionising. On the other hand, radiation can be either electromagnetic wave motion or or particle radiation.
Ionising radiation has enough energy to remove electrons from a substance exposed to radiation or break molecules. Radioactive materials emit ionising radiation. X-ray devices also produce it.
Non-ionising radiation is electromagnetic wave motion. Non-ionising radiation is utilised in mobile phones and microwave ovens, among other applications. The ultraviolet radiation from the sun is also non-ionising.
Ionising radiation can damage the DNA of living cells. From the point of view of damage to cells, it does not matter whether the radiation is natural radiation or man-made radiation. However, it is significant whether a radiation dose is received over a short or long period. Even a small radiation dose increases the risk of cancer slightly. A high radiation dose received during a short period can destroy a lot of cells and cause radiation sickness, local injury or foetal damage.
The ultraviolet radiation from the sun and solarium equipment, on the other hand, causes skin cancer.
