Date: 10/20/14 Angineh A. Zohrabi GE150 Unit 5 Assignment 1: Radioactive Tracing Technology Radiation facts and health effects Radiation is a form of energy. It comes from man-made sources such as x-ray machines‚ from the sun and outer space‚ and from some radioactive materials such as uranium in soil. Radiation travels as rays‚ waves or energetic particles through air‚ water or solid materials. Radioactive materials are composed of atoms that are unstable. As unstable atoms become stable‚ they

In pregnant women this radiation‚ in any dose is especially harmful to their soon to be baby. i. In a New York Times article commemorating the life of physicist Ernest Sternglass‚ it was stated that Sternglass first discovered that exposure to x-ray radiation in pregnant mothers harmed their developing fetus and caused higher rates of infant mortality and childhood leukemia. ii. It is possible to compare the amount of radiation you receive from one x-ray procedure and compare

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

ABSTRACT The effect of radiation to the production and growth of corn (Zea mays) w studied by irradiating the corn kernels with different doses (0‚ 10‚ 30‚ and 50 kilorad) of gamma rays. Ten kernels of corn was planted for each doses starting with the control one up to the 50 kilo rad. Each day it was observed‚ measured‚ and count the corn plants that grow and died. During the first day of observation‚ there are six corn plant that grow in the control‚ 10‚ and 30‚ and there is no plant that grow

Radiography is the most familiar type of radiation technique and it uses electromagnetic radiation instead of visible light and this type uses the smallest amount of radiation. Electromagnetic radiation is produced when charged particles of sufficient energy hit a material. Computerized Tomography commonly known as a CT scan‚ during this procedure the patient ties on the table and enters a ring-shaped scanner and this type uses the highest dose of radiation because so many images are taken at once

Power Note: nuclear power works by radioactivity “Radioisotopes are naturally occurring or synthetic radioactive form of an element. Most radioisotopes are made by bombarding a stable element with neutrons in the core of a nuclear reactor. The radiations given off by radioisotopes are easy to detect. Most natural isotopes of relative atomic mass less than 208 are not radioactive. Those from 210 and up are all radioactive.”(Radioisotope - Hutchinson Encyclopedia) (Radioisotopes image) An example

work with radioisotopes due to the safety concerns. There is a risk of radiation when working in close contact with the nuclear reactions. This is because radioisotopes release radiation when they are being produced. Radiation has the power to detach an electron from an atom‚ which can lead to destruction and mutation of cells. Since radiation has this ability‚ and humans are composed of many cells‚ if there is enough radiation exposure‚ it can cause serious harm to health. One more drawback of radioisotopes

Transuranic Elements and their Production Transuranic elements are elements that have an atomic number greater than 92. Transuranic elements have been synthesised in nuclear reactors or in high-energy particle accelerators. Neptunium and plutonium were the first transuranic elements to be synthesised in 1940 by Glenn Seaborg’s research team in the USA. Uranium 238 is bombarded with neutrons produced by the nuclear fission of U-235. Initially an isotope of uranium (U-239) forms which decays

we learned that there are 7 types of radiation of the electromagnetic spectrum – gamma rays‚ x-rays‚ ultraviolet‚ visible spectrum‚ infrared‚ microwaves and radio waves. With different wavelengths‚ they each have different properties and uses. Gamma rays are the radiation with the smallest wavelengths – 10-12m to 10-10m – and the most energy and the most danger of any wave in the electromagnetic spectrum. Radiotherapy‚ a treatment the use of high-energy radiation‚ is the most well-known way of how

This half life is long enough for it to be transported form where it is produced to where it needs to be used but it is also short enough to minimise patients exposure to radiation It decays into non-radioactive gas‚ Xenon 131‚ which can easily escape without interfering bodily functions Beta particles can destroy abnormal tissue.
