Radium-226 is a decay product of 238U . 226Ra has a half-life of 1600 years and is found in uranium ores

Radium-226 is a decay product of 238U . 226Ra has a half-life of 1600 years and is found in uranium ores. When it was first discovered and before radioactive decay was well understood, some mineral prospectors claimed to have discovered a rich deposit of radium (a few percent by mass) in a cave in the American midwest. What do you think of this claim?

The Plutonium isotope 239Pu has a half-life of 24,000 years and decays by the emission of...

The Plutonium isotope 239Pu has a half-life of 24,000 years and decays by the emission of a 5.2 MeV alpha particle. Plutonium is not especially dangerous if handled because the activity is low, and the alpha radiation doesn’t penetrate the skin. However, there can be serious health concerns if the tiniest particles are inhaled and lodge deep in the lungs. This could happen following any kind of fire or explosion that disperses Plutonium as dust. a) (3 pts.) Soot particles...

Carbon 14 (C-14), a radioactive isotope of carbon, has a half-life of 5730 ± 40 years. Measuring the amount of this isotope left in the remains of animals and plants is how anthropologists determine the age of samples. Example: The skeletal remains of the so-called Pittsburgh Man, unearthed in Pennsylvania, had lost 82% of the C-14 they originally contained. Determine the approximate age of the bones assuming a half-life of 5730. (a) 14,000 years (b) 15,000 years (c) 17,000 years...

The half-life of a radioactive isotope represents the average time it would take half of a collection of this type of nucleus to decay. For example, you start with a sample of 1000 Oxygen-15 (15O) nuclei, which has a half-life of 122 seconds. After 122 seconds, half of the 15O nuclei will have decayed into Nitrogen-15 (15N) nuclei. After another 122s, half of the remaining Oxygen nuclei will have also decayed, and so on. Suppose you start with 3.71×10315O nuclei...
