Sources & Uses of Radiation
Radiation & Me. Many uses of radiation help to ensure the high quality and safety of our daily lives. Smoke detectors to warn us of fire, x-ray machines to detect weapons or other devices in luggage and cargo, and certain types of imaging to look for diseases are all application of radiation for the benefit of society.
Use of electromagnetic radiation from fractures for mining …
Abstract. This paper presents an electromagnetic radiation-based method to qualitatively assess mine-induced stress field at the longwall face. We first analyze the correlation between electromagnetic (EM) signals and stress, and then measure the signals and drilling bits in both the strike and dip directions at the 11702 working face of Nuodong …

Uranium mining and health
Uranium mining is the first step in the generation of both nuclear power and nuclear weapons. Nuclear power plants produce routine radioactive emissions in air and water, produce nuclear waste, and create conditions for disasters similar to Chernobyl and Fukushima. Physicians should be concerned about the health effects of the uranium …
What is Radon and How are We Exposed to It? | IAEA
Radon accounts for around a half of all human exposure to radiation. It is also the most important cause of lung cancer after smoking and the leading cause of lung cancer among non-smokers. According to WHO, radon is estimated to cause between 3% to 14% of all lung cancers. Depending on the average radon level indoors and smoking …
