Radioactive decay

How big is ‘small’? Is it a grain of sand, a speck of dirt, a strand of hair, a drop of water? Is it the size of what humans can see, with our own two eyes? Is ‘small’ bigger than that? Or is it much, much less? For years, people tried to discover the definition of small for the scientific world. Does ‘small’ act the same way as ‘big’? Can the movements of ‘small’ be described and categorized? All of these questions were analyzed over and over by scientist for hundreds of years, to form what is…

geometry. Stewart elucidates the importance of each equation by mentioning its uses in the modern world, like while logarithms are generally not employed now that we have inexpensive calculators and computers, but many measurements like sound, radioactive decay and earthquakes still employ logarithms. Calculus, invented by Sir Issac Newton, helps in incorporating the movement of the solar system bodies into one mathematical equation. The equation I could relate to most was Claude Shannon’s…

The two key attributes of atomic parting critical for the down to earth arrival of atomic vitality are both apparent in the second comparison above. In the first place, the vitality per parting is huge. In commonsense units, the splitting of 1 kg (2.2 lb) of uranium-235 discharges 18.7 million kwh as warmth. Second, the splitting procedure started by the retention of one neutron in uranium-235 discharges around 2.5 neutrons, on the normal, from the split cores. The neutrons discharged in this…

edge of space. Helium can be changed to liquid and gets cold enough to cool anything. A lot of helium is found in outer space as He atoms are inside stars. The helium we are familiar with that comes in cylinder tanks is made by the natural decay of radioactive elements in the outer layer of the earth. Most of this comes from natural gas deposits in wells found in Texas, Oklahoma and Kansas but some has been from Wyoming, Utah and Colorado.…

is found in all living things and is the building block for organic material, there is carbon 12, 13 and 14 and they all have different properties. This isotope was discovered on February 27, 1940 by Martin Karmen and Sam Ruben and is the most radioactive out of all carbon isotopes. The relative abundance of it is >0.1% (trace amount) and its relative mass is 14.003241. It has 6 protons and 8 neutrons. This particular isotope is found in all carbon containing substances however it is very…

Ferguson, president of the Federation of American Scientists, writes about how nuclear energy is formed, the health risks it can cause, and the cost of nuclear energy plants. He gives the three sources to create nuclear energy: fission, fusion, and radioactive decay. Farther into book Ferguson gives background information on nuclear energy and the health risks that can develop from it. People exposed to too much ionizing radiation over long periods of time are at a higher risk for developing…

gamma rays, electron beams and x-rays. Gamma rays and x-rays share the same characteristics with microwave oven but with higher energy and penetration (Palmer, 2009). However, gamma rays Cesium 137 or Cobalt 60 which are both naturally occurring radioactive decay. During food irradiation, the substance is pulled into a chamber with massive concrete walls that keep any rays from escaping, so the food is exposed to the rays for a defined period of time. Food Irradiation could be applied in…

knots. Since this work was based on notion of the Feynman Path, it made it not mathematically correct, which became the theory of Reshetikhin Turaev invariants. While working with another physicist, he wrote a paper about anomalies, which is radioactive decay, only studied in terms of topology, and in 10 dimensions. The M-theory is the theory that brought five different suggestions into equations and added dimensions, that suggests strings were membranes/branes. The membranes/branes could only…

used for production of high-energy X-rays. ("Uranium: Its Uses and Hazards.”) I will focus on the use of Uranium in nuclear power plants. Natural uranium consists of three isotopes: uranium-238, uranium-235, and uranium-234. Uranium isotopes are radioactive. Uranium-238, the most common isotope in uranium ore has a half-life of about 4.5 billion years. It is used for nuclear weapons and is most common. Isotope 235 is important because when it splits it releases a lot of energy, which is called…

are believed to have been formed millions of years ago. They are originally found in the extreme temperature and pressure of the upper mantle of the earth’s crust. Diamonds have a radioactive isotope in it called carbon-14 and would not be existent if diamonds didn't have it. But according to the rate of carbon-14 decay, it is found to last about 5,730 years. Ordinarily if it were to last 5,730 years then why are diamonds which have supposedly been for millions of years still here and fine. One…
