Ionizing radiation

objects such as rocks or carbon by using the decay rate of radioactive isotopes. It has been used since its invention by Ernest Rutherford in 1905. Radioactive decay itself, is the process by which an unstable atomic nucleus loses energy by emitting radiation. Each radioisotope decays at its own fixed rate and this is measured in half lives. As discussed in Lesson 6, this is the time it takes for half of a parent element (e.g. uranium) to decay into a daughter element (e.g. lead) [1]. A common…

material's low-energy gamma rays to be used in some cancer treatments while the alpha radiation emitted minimally effects the contaminated host (Wanless, A., 2011). Americium can be useful to humans, despite its radioactive state as it is used in testing devices such as fluid gauges, thickness measurements, and is also used in the production of domestic smoke detectors. Exposure to ingestion results in internal radiation and the material can then be transported through the circulatory system of…

According to Samuel S. Epstein, Cancer prevention expert and Prof. Emeritus at University of Illinois School of Public Health in Chicago as well as Founder/Chairman of the Cancer Prevention Coalition, “Of more than 100 radioactive chemicals in fallout, Sr-90 was the most feared. This radioactive fallout, as it is called, carries something that’s called strontium-90, which is the most dreadful poison in the world. For only one tablespoon equally shared by all the members of the human race could…

Uranium, which are found in soil and rock throughout the world. This radon then breaks down into solid radioactive elements which are called radon Progeny. This radon progeny can then attract to air particulates and if inhaled can give off high energy radiation which can damage the DNA inside the body’s cells. In comparison with Radon in outdoor air, humans confined air spaces, such as mines and buildings, are exposed to higher concentrations of radon. The levels…

treatment can be classified as radiation therapy. The radiation that specific isotopes give off are utilized for effecting cancer cells. First of all, what is radiation? Radiation is energy that is carried by waves of streams of particles. The energy from radiation damages the genes (DNA) in the cancer cells. The damage done to the cells prevent them from growing and dividing, and often cause them to die off. Nearby normal and healthy cells can also be affected by the radiation. However most…

What if you found out your cell phone could kill you? Radiation is part of our natural world; however, it is often dramatically increased by man made objects (Gould, 2017). There are many different things to know about radiation, and questions to ask including what objects give off radiation, the dangers involved in radiation, and symptoms of radiation sickness. The radiation of everyday objects and the different types of radiation effect the human body in many ways which can sometimes be…

Radiation is defined as emission of energy in the form of x rays and gamma rays. It is transmitted from one place to another. Ionizing radiation is high energy waves that pass the body's tissue, that produces positive and negative charged particles. These high energy waves remove electrons from atoms and cause an interaction between the x rays and the patient. This process is referred to as ionizing radiation. The amount of energy acquired from ionizing radiation is absorbed into the patients…

Radiation therapy is used in the treatment of approximately 40% to 60% of patients who are diagnosed as having cancer.1,2 Radiation therapy uses ionizing radiation delivered by external beam therapy or radioisotopes with either a palliative or curative goal.1 These complex treatments are usually delivered daily during a period of five to seven weeks.1,2 Radiation therapy is recognized as a high-risk procedure because of the number of steps and staff involved.3 The radiation oncologist, medical…

course of treatment (2). Radiation therapy involves exposure to normal tissues as well as the tumor tissue and can cause damage to the normal cells because of the high energy of the gamma and X-ray (1). All molecules in the cell including lipids, proteins, carbohydrates and nucleic acids have potential to receive damage by radiation. However, deoxyribonucleic acid (DNA) because of its function is the most important molecule in the cell which will be affected by ionizing radiation. Gamma and…

radiographer should take the important responsible in radiation protection of the patient, member of the trauma team, and the radiographer himself or herself. Member of the trauma team cannot leave the patient in critical situation while imaging procedure are being performed. The unnecessary radiation exposure should be avoid and the trauma radiographer must unsure the team member are protected. In general radiography, common practices should minimal the radiation exposure include close…
