Electrons are boiled off from the cathode of an x-ray tube. They are accelerated to high speed by a potential difference to strike the anode also known as the target. The incident electron interacts with an inner shell electron of the target material this creates a vacancy in the shell. An electron from an outer shell fills that space and releases energy in the form of an x-ray of characteristic wavelength for the target material. When an x-ray is release by a L shell electron falling into a K shell

Radioisotopes are radioactive isotopes of an element. An isotope is an element’s atom that has the same number of protons and electrons‚ but a different number of neutrons‚ causing the atom to be unstable. With radioisotopes‚ they can occur naturally‚ but most often are formed artificially by altering the atom. Scientists measure the rate of which radioisotopes decay at by using the term half-life. This refers to when one-half of the radioactive material has decayed. When the word radioactive comes

Max Gomez September 25‚ 2013 Public Speaking‚ SPC 2608 Professor Grimaldo Ray “I was born with music inside me. Music was one of my parts. Like my ribs‚ my kidneys‚ my liver‚ my heart. Like my blood. It was a force already within me when I arrived on the scene. It was a necessity for me-like food or water.” Ray said. Ray Charles Robinson was a pioneer in the genre of soul music during the 1950s by fusing rhythm and blues‚ gospel‚ and blues styles. He was blind. He started to lose his sight

It is used in diagnostic scintigraphy‚ which is a study to asses organ function. Most frequently used‚ isotope of technetium-99m allows the quick removal of the radioisotope from the body and minimizes the risk of possible complications. Unlike X-ray studies‚ which better illustrates the structure of the organ‚ scintigraphy allows accurate diagnosis of its activities and the early detection of any abnormalities. In therapy‚ radioactivity has found its place primarily in the treatment of cancer

Nuclear Chemistry Imagine the majority of Earth being quarantined off and people having to live in specified areas to avoid harmful radiation that originated from nuclear energy/waste. The integration of nuclear energy/medicine is largely controversial among people. Every side to the argument has its benefits as well as its negative consequences. Nuclear energy should not be used in society because of the threat it poses to thousands of people. In contrast‚ nuclear medicine has positive aspects that

DDT and Radium Exposure In our country’s past‚ new and untested dangerous materials could be found in many places. Two of these materials were DDT (dichlorodiphenyltrichloroethane) and Radium. Both These two materials were both similar and different in many ways. Radium and DDT are similar in a few ways. Both are very rarely found existing in nature. They are similar in that Radium is often found only in compounds and DDT is a compound. Besides that‚ they both harm the human body. They both mainly
