Radioactive decay

Bianca Gomez Mr. Lewis Honors Chemistry 17 November 2017 Radon-Engineer Introduction: Radon is a colorless/odorless gas that comes from the radioactive decay of Uranium. Radon is commonly found in soil and is usually exposed to human beings through ingestion and inhalation. Most of Radon exposure is seen in many homes that are located in places where the soil beneath it contains a high concentration of it. Radon has been seen more often through sicknesses of people who are exposed to it, for…

technetium-99m is an isotope of the artificially and it has many characteristics for nuclear medicine scan the first one it has a half-life of six hours and it decay by process called “ isomeric ” and emit low energy of gamma rays and this helps to easily exit the body and can be detected accurately also emit beta rays but without high energy radiation dose to the patient is low . It has different number of…

Another example of a radioactive contamination can be found in the human-made product Americium (Am). This radioactive material is the unstable result of nuclear production and testing of uranium and plutonium. Impacts of Americium on the human body allows this 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…

cancer whilst minimising the damage to other tissue. For curing cancer the radiation needs to be very carefully targeted and controlled, so the radiation is produced by a powerful X-ray machine. With internal radiation therapy, a small amount of radioactive…

“If you look at the evolution and leap forward to 11 years from now, I think we will be using all the knowledge in molecular biology, and cancer biology combined with imaging, It will be images, combined with genes, tumor markers and patient data.” (Liselotte Hojgaard, MD, professor of medicine and technology at the University of Copenhagen) The science of radioactivity has existed for many decades since it’s discovery. While often perceived as a risky and dangerous practice, artificial…

Introduction: This was an unannounced office safety inspection of this analytical x-ray registrant, which is located at 1927 Commercial drive, Port Allen, West Baton Rouge Parish, Louisiana. The registrant owns and operates one x-ray fluorescence (XRF) analytical x-ray unit, Thermo Fisher Scientific, model XL3t 980, serial numbers 92731, which is routinely utilized to perform alloy analysis of metals. This is the first inspection of the facility. One area of concern was revealed during the…

The girls were blind to the true effects of radium; in fact, most everyone in that time period thought that all forms of radium were good for you. Back then, radium was like Aloe Vera today, it was used for a wide variety of causes, believed to improve overall health. People believed that radium could cure anything, from arthritis to high blood pressure- it was even once believed to be the absolute cure for cancer when ingested. Radium, found in uranium, is actually a rare chemical element of…

Chapter Six: Completing the Table…with a Bang 1. What is the difference between a “dirty” bomb and a conventional nuclear bomb? (1 mark) The difference between a “dirty” bomb and a conventional nuclear bomb is that a nuclear bomb is designed to destroy organisms using heat and impact, while a dirty bomb is designed to kill with gamma radiation. Radiation from dirty bombs, besides burning through skin, also alters the DNA in bone marrows, which significantly weakens the body’s immune system, and…

Most individuals with even the most rudimentary knowledge of science have probably heard of x-rays and gamma radiation. Very few however, will be able to tell you where these forms of radiation come from. The answer: Pulsars. Pulsars, or neutron stars, are physics sandboxes that provide extreme conditions for humans to experiment with which are not readily available on Earth. Due to this usefulness, the discovery and research of these phenomena should be of the utmost importance. These neutron…

Paragraph 1 The structural evolution of FePO4 studied from a temperature range of 294K to 1073K by neutron powder diffraction. It is unique from α-quartz isotopes. It is different because it’s a cation is a transition metal. The structure dimensions and atomic coordinates in the α phase tend to increase by great amounts as the high-temperature β-phase rises and exhibit first order transition at 980K. The atomic structure dimensions of the α-phase FePO4 increased in a non-uniform pattern with…
