Comparison of side effects‚ limitations and risks. For the both ionising and non-ionising radiation there are many side effects‚ risks and limitations. In ionising radiation‚ there is a risk of cell mutation which can result in developing cancer if there is overexposure of the radiation to the patient’s. In the worst state this radiation can result in death. This type of radiation is not recommended to the groups of people like children‚ pregnant women or the elderly as it will expose them to higher
