Radiation Therapy Program Ever since I was a child‚ I wanted to become a nurse. My father was always in and out of the hospital as a result of diabetes. One of my earliest memories is of him telling me to become a nurse so that I can take care of him. He passed away when I was ten years old. As a result‚ I devoted my school career to pursuing a nursing degree‚ seeing as it was what my father wanted. That was until my grandmother was diagnosed with breast cancer in March 2007. I accompanied

chemical symbol identifies the element it is redundant to include the atomic number‚ so it is rarely used. Carbon-14‚ therefore‚ would be written as 14C or C-l4. Unit of Radiation Energy The electron volt (eV) is an extremely small unit and is equal to only 1.6 X 10-12 ergs. It is only used in radiation safety to express radiation energy. The electron volt is such a small unit that it is usually written as mega- or kilo- electron volts which is a million electron volts (MeV) or a thousand electron

Cell Phone Radiation Written by: Jacob Nickerson Cell phone radiation is something we as consumers are exposed to each and every day. What effect does this have on us? Can this radiation alter the cell structures and functions of our bodies? For what amount of time can our bodies be exposed to this radiation without health risks? These are all questions many scientists and researchers are trying to answer with every day that passes. Researchers are divided on a conclusion of whether or not

word ’radiation’ has to do with energy or matter moving through space. Space radiation affects astronauts when an amount of radiation gets through the walls of a space shuttle or station and enters the body. Solar radiation usually affects astronauts walking in space‚ outside of their space shuttles‚ but sometimes it can even affect the people on Earth‚ causing electricity failures. Many people - astronauts mostly- fear the consequences of solar radiation‚ due to the fact that solar radiation can cause

The History of the Discovery of Radiation and Radioactivity Introduction: Radiation can be defined as the propagation of energy through matter or space. It can be in the form of electromagnetic waves or energetic particles. Ionizing radiation has the ability to knock an electron from an atom‚ i.e. to ionize. Examples of ionizing radiation include: • alpha particles • beta particles • neutrons • gamma rays • x-rays Non-ionizing radiation does not have enough energy to ionize atoms in the material
