Ionizing radiation can damage living tissue in the human body. They may cause electrical shocks and burns. CDC twenty four seven. Low-frequency magnetic fields induce circulating currents within the human body. Chemotherapy side effects depend on the chemotherapy treatment as there are varied types of chemotherapy medications. Radiations also differ in the power to penetrate. Follow @Medindia You will be subject to the destination website's privacy policy when you follow the link. Always seek the advice of a qualified physician for medical diagnosis and treatment. There are strict advisory limits for exposure to even higher energy radiation levels such as medical x-rays and gamma rays, which can both lead to damaging effects within the human body. Alpha and beta, gamma and X-rays particles are the most common forms of ionizing radiations. the LET of diagnostic x-rays is : 3.0 keV/um. Most nuclear accidents release radioactive iodine into the atmosphere. Spontaneous decay of radioactive materials produces radiation. Charged particles react with the earth’s atmosphere to produce secondary radiation which reaches the earth. Cosmic radiation exposes the body to radiation in a manner similar to exposure from a medical X-ray. NRC: Glossary – Cosmic Radiationexternal icon.
