Radioactive dating for middle school
Strictly speaking, gamma emission isn't 'radioactive decay' because it doesn't change the state of the nucleus, it just carries away some energy. You can think of different isotopes of an atom being different "versions" of that atom. It has 6 protons and 6 neutrons - we call it "carbon-12" because it has an atomic mass of 12 (6 plus 6).If we add a neutron, it's still a carbon atom, but it's a different isotope of carbon.Video taken from WFTS-TV's helicopter last week showed a built-up ring around the hole as crews have begun pumping the mixture inside.The sinkhole, which measures 45 feet in diameter and is 300 feet deep, opened up beneath a pile of waste material at Mosaic, the world's largest supplier of phosphate.So isotopes of an atom have the same number of protons, but a different number of neutrons.Growing up in suburban Detroit, David Hahn was fascinated by science.Joyce Hunter, who lives a couple miles from the plant, said that she doesn't drink the water at all.
She and her neighbor, Ron Lynn, say they are just praying the radioactive water that got sucked into the hole doesn't reach their private wells.Mosaic has built a concrete plant nearby to keep pumping concrete into the hole during this 'stabilizing phase'.The nucleus consists of protons (p) and neutrons (n), and is extremely small. ) In some types of atom, the nucleus is unstable, and will decay into a more stable atom. It's not the same as what happens in a nuclear power station (where neutrons whizz around and hit uranium nuclei, causing them to split).While he was working on his Atomic Energy badge for the Boy Scouts, David’s obsessive attention turned to nuclear energy.Throwing caution to the wind, he plunged into a new project: building a model nuclear reactor in his backyard garden shed. Following blueprints he found in an outdated physics textbook, David cobbled together a crude device that threw off toxic levels of radiation.
Video taken from WFTS-TV's helicopter last week showed a built-up ring around the hole as crews have begun pumping the mixture inside A storage pond containing 215 million gallons of radioactive water sat atop the waste mineral pile and drained into the aquifer system, which supplies drinking water to millions of residents.
