Since the atmosphere shields us from the cosmic rays, the higher we go in our atmosphere, the more radiation we are subject to. Therefore the amount of instantaneous radiation is larger when travelling on an airplane, compared to staying on the Earth's ground. For example, a long-distance airplane flying at cruising altitude exposes each passanger to an extra dose of radiation of about 5 μSv per hour. Now, assume that, for anyone who is not taking any flights, the natural background exposure in a year is 3 mSv, and assume also that there are no other significant sources of radiation. After how many hours of flying would a person double her or his yearly radiation dose? Express your answer in hours. 195| ΑΣΦ t= ? h
Radioactive decay
The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. This periodic table's elements come in a variety of shapes and sizes. Several of these kinds are stable like nitrogen-14, hydrogen-2, and potassium-40, whereas others are not like uranium-238. In nature, one of the most stable phases of an element is usually the most prevalent. Every element, meanwhile, has an unstable state. Unstable variants are radioactive and release ionizing radiation. Certain elements, including uranium, have no stable forms and are constantly radioactive. Radionuclides are elements that release ionizing radiation.
Artificial Radioactivity
The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.
