Radioactive contamination

ultrasounds do not use radiation. Even though people will attempt to avoid radiation, it will build up inside them and it will never leave. Though the technology of radioactive imaging individuals have been able to provide images of the inside the body that have assisted medical professionals avoid exploratory surgery. Different types of radioactive imaging use ionizing radiation to produce these images. Some of these are X-rays, PET scans, and CT scans. However, since this imaging uses…

The toxin Radon is a natural radioactive gas that is odorless and tasteless. It is really helpful with cancer therapy. It was initially used in hospitals to treat tumors and to help cure the illness. Radon has a half life of around four days, meaning half of any given amount of radon can decay other products for four days. Other parts of Radon is produced in the soil and gets exposed in the air. It moves from the soil to groundwater, which can be harmful because it gets into our drinking water.…

What is radioactive dating? and how does it work? Radioactive, or Radiometric dating is a technique used to determine the age of 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,…

Radioactivity has had a great impact on the medical field especially with x-rays. Marie Curie was one of the main researchers on the radioactivity used for these. Not only did she study and research the material, but she also saved millions of people during World War 1. (Funk & Wagnalls) Marie Curie’s passion for science and physics was and is, as illuminating as the glow from the element radium she is known for discovering. She has left a magnificent imprint on the world of science and…

Although undetected by sight, smell, or taste, this radioactive gas has led to an estimated 20,000 lung cancer deaths each year. Radon is a cancer-causing radioactive gas that can be found outdoors and indoors. It is a naturally occurring gas that comes from the radioactive decay of 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…

In today's millennial society all of us are so accustomed to going to a local grocery store or market to pick out the goods they have in their selection. What we fail to sometimes realize is how those goods came to be as well as what measures were taken in order to ensure the product is safe for human consumption. We as humans sometimes fail to realize the how far agricultural ideology has come in the last 50 years. Rachel Carson highlights throughout her 1962 book “Silent Spring”. Although it…

We focused on arsenic exposure health risk analysis through oral ingestion and dermal absorption pathways of groundwater in the present study. The local residents in the study area were interviewed for basic information such as age, sex, body weight, health status, socio-economic status, food habits and drinking water sources. It was mentioned that the residents were using mainly groundwater for drinking and other purposes. The poverty, lack of awareness and having no effective alternatives were…

fossil fuels and was even referred to as the energy source of the future. To the uninformed the use of nuclear energy may seem frightening because the only thing rumored is the negatives like: the waste, major spills of material and disastrous radioactive accidents, but there are many benefits from the use of this energy source such as: saving millions of lives, a mass reduction of pollution, and an advancement of technology. Although it may take a long time, society will benefit from this…

Over christmas vacation in 1938, nuclear fission was a startling discovery made by Lise Meitner and Otto Frisch. The discovery immediately revolutionize nuclear physics and a lead to the atomic bomb. This essays discusses the building of a nuclear power plant South St. Paul, Minnesota. I am arguing that we should not build a nuclear power plant in South St. Paul, MN. It takes on an average amount of fifthteen years to build. There could be a nuclear accident, such as a nuclear meltdown. Also…

produces 250,000 tons of carbon dioxide every year. So nuclear power won’t really help very much in the fight against global warming. (Clayton). Other energies such as wind or solar not only produce less carbon dioxide, but also don’t leave behind radioactive waste that remains dangerous for hundreds, if not thousands, of years (Clayton). But even if you don’t care about the environment, there is one thing that everyone does care about; money. Nuclear power comes with an exorbitant…
