In this simulation‚ you can input the temperature and observe the spectrum of the radiation emitted. a) The temperature of stars in the universe

radiating electric field (or electromagnetic signal) produced when radio stations broadcast? Include a description of what is producing the signal as well as the reasoning behind how this could produce a signal. We know that electromagnetic radiation is produced by accelerating charges. In the radio transmitter‚ electrons oscillate up and down and are thus accelerating. An electron will exert a force on another electron when they are some distance away‚ like charges repel. When the electron in

Chernobyl‚ Ukraine Nuclear Power Plant Meltdown The accident at the Chernobyl Nuclear Power Plant in Ukrainian produced a plume of radioactive debris that drifted over parts of the western USSR‚ Eastern Europe‚ and Scandinavia. The accident‚ which occurred on April 26‚ 1986‚ was the worst nuclear power accident in history. Large areas of the Ukrainian‚ Belorussian‚ and Russian republics of the USSR were contaminated‚ resulting in the evacuation of roughly 200‚000 people. The accident raised

types of radiation surrounding us. As human beings‚ we are primarily exposed to natural forms of radiation such as radon‚ cosmic (space) radiation‚ and naturally occurring radioactive elements found in the Earth. We are also exposed to man-made radiation including medical radiation. Nearly half of the radiation in which the US population is exposed to comes from medical sources such as CT scans‚ x-rays‚ and nuclear medicine. In 1899‚ Ernest Rutherford discovered that the radiation emitted by

NEGATIVE PHYSICAL EFFECTS OF NUCLEAR RADIATION Page 1 Abstract Nuclear radiation has been a major problem since 1941 when the Second World War began. A major contribution to World War Two is the nuclear bomb‚ also known as the Atom bomb. Once the two bombs were dropped‚ the usually terminal Leukemia was derived throughout Japan. There are three types of radiation‚ Alpha‚ Beta‚ and Gamma radiation. In my study of radiation I discovered that radiation can damage many cells in your body as

of Computer Radiation in the Health of I-BSN-2 Students of Cavite State University I. Introduction Nowadays‚ computers are very common in a household. Computers are very advantageous which actually has unlimited capabilities; in seeking a certain information‚ for recreation‚ for entertainment purposes and many other uses. But despite those infinite uses of computers‚ some say that computers cause detrimental effects to those who are exposed to its radiation. Radiation‚ in Physics

PHY 114: General Physics Laboratory Lab 1: Absorption of Nuclear Radiation 09/04/13 Abstract Nuclear physics was practiced to find the value of tau. After 8 trials of using a G-M counter and 8 different mass thicknesses of polyethylene‚ a graph was formed and tau was calculated to be 0.1931 cm^2/g‚ an error of 3.57% from the accepted value of 0.2 cm^2/g. Experiment was also used as an intro to using basic lab equipment‚ computer programs and calculating errors. With many different

died at the time from a coronary thrombosisc. Acute radiation syndrome (ARS) was originally diagnosed in 237 people on-site and involved with the clean-up and it was later confirmed in 134 cases. Of these‚ 28 people died as a result of ARS within a few weeks of the accident. Nineteen more subsequently died between 1987 and 2004 but their deaths cannot necessarily be attributed to radiation exposured. Nobody off-site suffered from acute radiation effects although a large proportion of childhood thyroid
