Radiofrequency (RF) radiation is at the low-energy end of the electromagnetic spectrum and is a type of non-ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to ionize (remove charged particles such as electrons).icrowave ovens work by using very high levels of a certain frequency of RF radiation (in the microwave spectrum) to heat foods. When microwaves are absorbed by food containing water, it causes the water molecules to vibrate. This produces heat.
The term radiosensitivity describes how likely the cell is to be damaged by radiation. Cancer cells tend to divide quickly and grow out of control. Radiation therapy kills cancer cells that are dividing, but it also affects dividing cells of normal tissues.The damage to normal cells causes unwanted side effects. Radiation therapy is always a balance between destroying the cancer cells and minimizing damage to the normal cells.he term radiosensitivity describes how likely the cell is to be damaged by radiation.
