2012) Exposure to UV radiation is the leading cause of most skin cancers as it induces DNA damage in skin cells. The effects of UV radiation can be classified based on the amount of exposure as acute or chronic. Acute side effects include sunburns and chronic effects can be mutagenic and also increase aging in humans. (Pacholczyk‚ 2015) The effects of UV radiation are significant and finding

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.

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

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).

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

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
