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

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

information on every organ system in the body. Nuclear medicine is a special branch of medicine or medical imagery. It uses radioactive isotopes that rely on the process of unstable atomic nucleic emission of ionizing particles and radiation to diagnose and treat disease. Radiation looks at both the function and the anatomy of the body to establish a diagnosis and treatment. The tests use small amounts of radioactive material to assist with diagnosis. Radiopharmaceuticals or radiotracers are the radioactive

What is cancer? Cancer is a disease in which an abnormal cell divides uncontrollably and destroy the body’s tissues. “1 out 2 men will get cancer in their lifetime‚ 1 out of 2.7 women will get cancer in their lifetime” according to the article When someone has cancer‚ by the American Cancer Association. Many people are unaware the great epidemic that cancer has now become. There is a myth with cancer that is it not hereditary‚ many do not accept the truth behind cancer. The important concept that

PURPOSES? In terms of definition‚ Electromagnetic Wave is a “non-particulate radiation (radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge)”. Thus‚ in simpler words‚ electromagnetic is a transmission of energy‚ caused by the oscillation and of electric and magnetic fields. The word electromagnetic wave or electromagnetic radiation may sound complex. However‚ without even noticing‚ electromagnetic waves have

The only one of the three mechanisms of heat transfer that does not require atoms or molecules to facilitate the transfer process” (Trefil & Hazen‚ 2010). Radiation traveling in the form of electromagnetic waves; energy that travels and spreads out as it goes (Trefil & Hazen‚ 2010). Below are everyday examples of the seven types of radiation that were seen on Figure 6-18. 1. Gamma

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

Radios and microwaves both use radiation from the electromagnetic spectrum Visible light can be split into a spectrum of colours .. from red through the rainbow colours to violet but visible light is just a small part of the whole electromagnetic spectrum All the different types of electromagnetic waves travel at the same speed through a vacum .. the waves can be orderd by wave length remebered that waves with the shortest wave lengths have the highest frequency and the most energy and the waves

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

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
