WebThis gives it a non-zero charge. When radiation passes close to atoms it can knock out electrons, ionising the atom. Alpha radiation is the most ionising form of nuclear radiation. This is because alpha particles have a charge of +2. Gamma radiation is the least ionising form of nuclear radiation. WebUnstable nuclei decay by emitting high energy particles or waves As the radiation moves away from the nucleus, it takes some energy with it This reduces the overall …

WebIonisation is the addition or removal of an electron to create an ion. Losing an electron creates a positive ion. Gaining an electron creates a negative ion. An atom's charge can … WebWhen alpha, beta or gamma radiation collides with human cells, it can ionise the molecules inside which causes damage to the cells and tissues. Ionisation can also result in DNA mutation. A mutation is when the code in the DNA changes, causing the cell to rapidly divide and become a cancer.
