An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 131 g (HINT: Assume all the carbon is 12c and determine the number of atoms) and careful measurements show that the remaining 14C has a current decay rate of 30 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of 14C to 12c when the animal died was 1.3x10-12 & the half-life of 14C is 5730 y. age of bone =
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.
