An archeologist discovers the bones of a person believed to have been dead for 600 years. Using carbon dating, they wish to confirm the time of the person's demise. The rate of change of 146C is 0.270 Bq/g of carbon for the bones of a person who had just died. If the archeologist is correct about the person's time of death, what rate of 146C change of should they find when they carbon date the bones? The half life of 146C is 5.73 x 103 y. A. 0.245 Bq/g B. 0.267 Bq/g C. 0.251 Bq/g D. 0.238 Bq/g E. 0.259 Bq/g
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.
