Radioactivity

observations of the fluorescence which led him to the discovery x-rays. Following Roentgen footsteps, in 1896 Antoine Henri Becquerel He conducted an examination using salt and plates wrapped in photographic paper and placed it inside a dark place. Becquerel believed that the final product would only demonstrate a slight imprint of the salts, yet to his surprise it left detailed imprints of the salts; he had discovered radioactivity or radioactive decay. Marie Curie thought of the term radioactivity despite of being Becquerel who discovered radioactivity. Alongside her husband Pierre Curie, Marie was able to discover two new radioactive elements, Polonium and Radium, thanks to a machine her husband and brother made. Another contributor on the discovery was Ernest Rutherford who studied the diverse properties of radioactive decay: alpha, beta and gamma particles. Although some of them died to over exposure of radioactive material, their diligent work and devotion affected present day physical science and what we know of radioactive rot today. Radioactive decay or radioactivity is present in numerous items we use in our daily lives from the water we drink to the air we inhale. The exposure of radioactive decay humans face in their daily lives can be man-made or naturally occurring. Radioactive decay helps scientist explore radioactive dating: which is the procedure for deciding the age of an item by calculating the measure of given radioactive material the object contains.…

which can lead to cancer (Gould, 2017). The damage radiation causes to living creatures and the environment can vary and is also created by different means. The EPA, also known as the Environmental Protection Agency, says “Protect human health and environment from unnecessary exposure of radiation” (Radiation Health Effects, 2016). The damage that occurs to life and the environment is an unnecessary occurrence. Rod Adams (2011) says, "100,000 deaths each year are calculated to result from…

A Radiological Dispersion Device, often referred to as an RDD or “dirty bomb”, contains conventional explosives (such as dynamite) and radioactive material. The intention is to spread radioactive material over a large area. RDDs are not a new idea. The military considered creating such devices in 1941. Dirty bombs are no longer considered practical for military applications and are now considered terrorist weapons (The Facts about “Dirty Bombs”, 2005, pg. 4). Radioactive materials are…

discovery of radiation and the start of the World Wars, the Unites States developed and publicized radioactivity, not caring for the immediate consequences, only hoping to win the war, become a world power, and understand radioactivity. The discovery of radiation led to the abuse of knowledge and power and ultimately led to the deaths of millions of people and the exploitation of an incredibly powerful force through lax safety regulations in factory environments, the promotion…

Radioactivity past paper assignment Question 1: In the fridge, from a previous experiment, there is a 50 mM [U-14C] glucose solution. A 20 uL aliquot was counted and gave 200 000 dpm. What is the specific activity of this preparation? 20 uL = 200 000 dpm (divide both sides by 20) 1 uL = 10 000 dpm Glucose = 50 mM = 50 mmol / uL = 50 umol/ uL = 50 nmol / uL Therefore in one uL = 50 nmol/ uL = 10 000 dpm (divide both side by…

History & Background (Fort MacMurray, Alberta) Nuclear power is a clean fuel, which results in little waste. In comparison with the traditional way of power generation, nuclear power is low-emission and high-efficiency in addition to being a carbon-free method of generating electricity. In this assessment, we are trying to figure out the contaminant sources of the nuclear power plant. The biggest threat for human’s health is the radioactivity of the chemicals which are being used to created…

Uranium is named after the planet Uranus because when it was discovered that was most recent planet discovered. Uranium nucleus is unstable and that’s why it’s radioactive. Uranium is in a constant state of decay, seeking a more stable state. In fact, uranium was the element that made the discovery of radioactivity possible. In 1897, French physicist Henri Becquerel left some uranium salts on a photographic plate as part of some research on how light influenced these salts. To his surprise, the…

effects on drinking water, landfills and wastewater treatment facilities are outstanding and a poor representation of what is being done to regulate fracking practices across the country. This pushes it's readers to think twice about the water they are drinking and what is really being done for the peace of mind of the rural citizen. With case-by-case interviews of people in the field of wastewater treatment and maintenance Ms. Brown brings strong logos to her article and uncovers how…

Some of these radioactive elements slowly break down to form radon gas. Radon is a concern for homeowners and most people are aware of its dangers. This could be why there is an overreaction to naturally occurring radioactivity in granite slabs. The amount of radon and radioactivity released from granite is quite small and rarely over the limits of natural background radiation. Also, radon occurs naturally in many places and you might have it in your house now if it seeps up through the ground…

The discovery of radioactivity took place over numerousyears. It began with the discovery of x-rays in 1895 by Wilhelm Conrad Roentgen and continuing with people such as Henri Becquerel and the Curie family. Wilhelm Conrad Roentgen (1845-1923) discovered X-rays. He received Nobel Prize for his discovery of X-rays in 1901. Antoine Henri Becquerel (1852-1908) was the first to discover that radioactive elements are distinguished existence. He received the Noble Prize for the discovery of…
