physicist and chemist who earned the title “Father of Nuclear Physics” after his discoveries of radioactive half-lives‚ differentiated between alpha and beta radiation‚ and proved that radioactivity involved the transmutation of one chemical element to another. He is also the recipient of the 1908 Nobel Prize in Chemistry "for his investigations into the disintegration of the elements‚ and the chemistry of radioactive substances". Ernest Rutherford was born in Spring Grove‚ New Zealand to his English

1. How much of our global energy supply do nuclear power‚ biomass energy‚ and hydroelectric power contribute? How much of our global electricity do these three conventional energy alternatives generate? Biomass provides 10.8% of global primary energy use‚ nuclear power provides 6.5%‚ and hydropower provides 2.2% of global primary energy use. Nuclear power generates 15.8% of the world’s electricity‚ and hydropower generates 15.9%. 2. Describe how nuclear fission works. How do nuclear plant engineers

about 7 mSv. Production: Irradiation of the stable oxygen 18 isotope with high energy protons (18 MeV) from a cyclotron. 8O18 + +1p1 ( 9F18 + 0n1. The target is either normal or enriched water. Half life: 109.77 minutes‚ which means that the radioisotope must be transported post haste. Ideally a nuclear medicine facility at a hospital would have its own cyclotron. Uses: Fluorodeoxyglucose: Fluorine is used as a radioactive tracer in PET Scans mostly as Fluorodeoxyglucose (more precisely

Question 3 A nuclear power plant (NPP) make used of its nuclear power to generate electricity. The expression “nuclear power” is defined as a controlled release of energy by nuclear fission or nuclear fusion reactions (Nuclear Power‚ 2004‚ p. 2809). The world’s first exposure to nuclear power came with the detonation of two atomic bombs over the Japanese cities of Hiroshima and Nagasaki in 1945 by the army of the United State of America (Nuclear Power‚ 2004‚ p. 2809). At that time‚ scientists believed

Chemistry Pg. 1 Carbon Dating Carbon dating is the most reliable‚ commonly used‚ and useful dating method‚ for what it can date. It is used to date late Pleistocene and Holocene artifacts and geologic events up to 50‚000 years decayed. Carbon dating has been very beneficial to the scientific world‚ because it is used in so many different fields of science‚ including archaeology‚ geology‚ oceanography‚ hydrology‚ atmospheric science‚ and paleoclimatology. The radiocarbon dating method was developed

CHAPTER 1 – GENERAL INTRODUCTION 1.1 Origin of Radon and Exposure Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive‚ colorless‚ odorless‚ tasteless noble gas‚ occurring naturally as the decay product of uranium. Radon is a gas produced by the radioactive decay of the element radium. Radioactive decay is a natural‚ spontaneous process in which an atom of one element decays or breaks down to form another element by losing atomic particles (protons‚ neutrons‚

Nuclear Medicine Nuclear medicine has been around for more than 50 years now and stems from the discovery of x-rays and artificial radioactivity. In 1946‚ nuclear medicine made a monumental breakthrough when radioactive iodine led to the complete disappearance of cancer in a patient’s thyroid. Nuclear medicine became widely used in the 1950’s to measure the function of the thyroid‚ to diagnose thyroid disease‚ and for the treatment of patients with hyperthyroidism. By the 1970’s nuclear medicine
