INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy

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

Lit 2 May 2013 History of Cancer: Radiation There is a broad group of different types of cancers and they all have a wide range of causes. Each cancer is different according to its biology and pathophysiology. Cancer is a very broad topic but chose four topics that show that radiation is the main cause of cancer. Before I can prove radiation is the cause of cancer‚ there needs to be an introduction as to what cancer is and how it spreads

EFFECTS OF RADIATION Background Radiation is all around us. It is naturally present in our environment and has been since the birth of this planet. Consequently‚ life has evolved in an environment which has significant levels of ionizing radiation. It comes from outer space (cosmic)‚ the ground (terrestrial)‚ and even from within our own bodies. It is present in the air we breathe‚ the food we eat‚ the water we drink‚ and in the construction materials used to build our homes. Certain foods

The year 2010 was a watershed moment in the field of radiation oncology‚ due to articles written by Walt Bogdanich in the New York Times. These articles critiqued leadership‚ radiation dose‚ and patient safety‚ and accused the community of using unsafe practices (Washington & Leaver‚ 2016). While there had been previous accidents which injured and killed patients during the 1980s‚ those few accidents were attributed to equipment faults‚ as computer equipment was merged with treatment delivery equipment

On the other hand‚ the usage of cell phone had become addictive to people of all around the world and the abuse of prolongated hours on the cell phones can cause health hazard. Cell phones work under a non-ionizing radiation bases. But there is still a concern of how much cell phone usage a person can endure without any harmful reaction to them. I myself believe that cell phones may cause a reduction of blood cell count‚ but I do not believe that cell phones causes
