Radioactive substances generated by ionizing radiation over a certain dose on the health of people. With a certain thickness of lead or concrete enclosed radioactive material, you can block this ionizing radiation. In nuclear power stations or industrial, medical and scientific research departments that use radioactive substances, they can be avoided as long as they are operated and managed in accordance with the regulations. Radioactive waste, whether gaseous, liquid or solid, should be stored below a certain level of ionizing radiation before being allowed to enter the environment. For ease of storage, often concentrated, concentrated exhaust gas and waste must be cured for disposal.
