WebDangers of Radiation. Ionising radiation can damage human cells and tissues. If the atoms that make up a DNA strand are ionised then the DNA strand can be damaged. If the DNA is damaged then the cell may die, or the DNA may be mutated when it reforms. If a mutated cell is able to replicate itself then a tumour may form. http://www.darvill.clara.net/emag/emagmicro.htm
