Cobalt-72, Cobalt-73, Cobalt-74, Cobalt-75 and Cobalt-76 (Jefferson Lab, n.d.). Co-60 is a synthetically produced radioisotope with a half-life of 5.27 years (Centers for Disease Control and Prevention [CDC], 2014). It decays through beta particles and gamma radiation (CDC, 2005). Cobalt-60 decays into stable isotope, Nickel-60 through beta minus decay (radioactivity.eu.com, n.d.). SAFETY ISSUES Cobalt-60 can be very dangerous to human health. If ingested or inhaled, the majority of co-60 is excreted

There are three different types of radiation, alpha radiation, beta radiation and gamma radiation all which can, in general terms can benefit human by usage in medical procedures to detect errors in the human body. However these radiation can also be the cause of defects and errors in the human anatomy. Alpha particles - Alpha particles are helium nuclei that contains two protons and two neutrons. Alpha particles are positively charged. They can’t travel easily through thin materials and can be

Radiation is the process of which energy is emitted either by particles or waves. (Radiation, n.d.) . Radioactive isotopes are chemical elements that have different masses and spare energy by emitting radiation in for of alpha, beta, and gamma rays. Gamma rays are photons with high energy and a very short wavelength of 0.0005 to 0.1nm. (What is Radioactivity? What is Radiation?, n.d.) Every chemical element has one or more radioactive isotopes, for example carbon, it has 3 isotopes with different

to examine, diagnose & treat patients without the need of surgical processes. This process is used to see what is beneath the skins and bones to find any abnormalities present. There are many types of medical imaging used, such as :- X-rays : these invisible beams can go through a number of objects, making it a fast and painless test done to be able to see inside the human body. This test is mainly used to see the bones and it depends on the amount of radiation absorbed and the density

nineteenth century, solutions have been introduced by scientists, that use radiation for the diagnosis of diseases instead of surgery (Pope, 1999), which has led to great advances in medicine because diagnostic technology such as CT and X-rays scanning, nuclear medicine (PET) and mammography,

and x-rays. Electromagnetic radiation covers a large spectrum of wavelengths, these waves of radiant energy have different usage according to their energy, in example; the rays from the sun, sunlight is vital to life on earth, radio waves allow us to communicate, microwaves allow us to cook our foods, infrared radiation provides us with warmth/heat, visible light illuminate and is also used essentially for growth of our trees, flowers, and the many foods we grow on earth, ultraviolet rays, which

radiotracers before the exam. These are drugs that are injected, swallowed, or inhaled as a gas that emit radio waves from the area being scanned. During the exam the radiotracers give off tiny amounts of energy also known as gamma rays. Special computers detect the gamma rays and interpret them into pictures of the area examined. Nuclear medicine imaging differs from other exams in the fact that regular exams picture the structure and anatomy or the body. Nuclear medicine imaging focuses on the chemical

some common medical procedures. X-rays and gamma rays are some of the most common types of radiation used in imaging tests. These rays let health care providers create images of the organs and tissues inside the body to help them make a diagnosis. Radiation can also change cells and sometimes destroy them. Exposure to too much radiation can cause health conditions such as cancer. WHICH PROCEDURES INVOLVE RADIATION? Imaging tests that use radiation include: • X-rays. • Mammograms. • Bone density

Science in the Media: Revolution Jessica Bradley NBC’s show, Revolution explores what life might be like almost 20 years after a worldwide blackout hits North America. The blackout in Revolution was an “artificially-caused apocalyptic event occurring in September 2012” (Revolution, 2014.) This event disabled all electricity. The blackout was originally a combat test on the Taliban, but a malfunction of Nanites caused a worldwide loss of power. 15 years later, power becomes briefly restored by the

But it’s still used for stress tests to see if they have coronary artery disease. Explain why this specific radioisotope is being used. (two or more sentences) It is used as a special camera called a gamma scintillation camera (which makes photographs from the gamma rays emitted by the thallium) can pick up if they previously had have a blocked heart or a blocked
