patient awareness and physician’s practice of defensive medicine. These issues have led to an increase in patient radiation dose every year. From 1996 to 2010 overexposure due to radiation has doubled. (Bardi‚ p.2) This is an alarming stat and shows that we need to really focus on this issue in the future. Another alarming stat is that Americans received seven times more radiation exposure from medical tests in 2006 than in the 1980’s. (Biomedical Instrumentation & Technology‚ p.359) I believe

From time immemorial human race knew that the ultimate source of energy for the earth is from the sun. Modern science has established that this energy is quantifiable‚ for better understanding‚ as electromagnetic radiation‚ EMR. Radiations

Ionizing radiation is radiation that can damage DNA and increase the risk of cancer tremendously. This form of radiation involves high-energy photons being absorbed by the body and penetrating the DNA (8). MRI differs from this because it uses non-ionizing radiation in the form of magnetic fields and radio waves and this type of radiation has not been linked to cancer yet. However‚ it is notable that most non-ionizing radiation is heat and patients run the risk of

early it has been detected. One method of treatment for cancer is Radiation therapy (Radiotherapy). This is the medical use of ionizing radiation to control or kill these malignant cells. However‚ there is doubt among society about the use of radiotherapy. This is mainly because some long-term side effects include the growth of scar tissue‚ infertility and damage to other areas of the body‚ depending on the location of the radiation treatment. Another major reason for doubting this treatment is because

Tips on Radiation Exposure CINCINNATI‚ Oct. 2‚ 2012 /PRNewswire-USNewswire/ -- With millions of X-rays performed on children every year‚ kids are more likely to receive X-rays than any other type of imaging exam. A new education campaign seeks to equip parents with the knowledge they need to make informed decisions about their kids and X-rays. Through a series of online teaching materials aimed at parents and medical professionals‚ Image Gently’s "Back to Basics" campaign promotes radiation protection

radioisotopes has increased our knowledge of biological processes and chemical reactions in humans and plants. New technologies: Geiger counter and Autoradiography. A Geiger counter is a type of particle detector that measures ionizing radiation. It is used as a handheld radiation survey instrument. Autoradiography is a technique used to trace the movements of certain substances around plants. The movement of the radioisotope can be traced by taking an autoradiograph. An autoradiograph is produced

contributed to earlier cancer detection in women. Dr. Wilhelm Conrad Roentgen discovered x-rays while working with a Crookes tube in his laboratory on November 8‚ 1895. Eighteen years later mammography got its rudimentary beginnings due to these ionizing x-rays. In 1913‚ Berlin Albert Soloman‚ a German surgeon‚ was among the first to discover that breast cancer could be radiographed. In a 1927 medical textbook the first instance of a radiograph of a living person’s breast taken by Otto Kleinschmidt
