Radioactivity

What if there was a way to clean up radioactive waste spills? To clean it out of waters for safe consumption? For years and years people have seen the ways that bacteria can clean up oil spills and nuclear waste, and where baffled on how they did so. How did something so small, clean up a mess so big? Gemma Reguera and her team at Michigan State have solved the age long question. They have decided that bacteria do so by a hair like pili. The pili acts much like a conductive wire, by transferring

Shortly after the discovery of X-rays, another form of strong rays were discovered. In 1896, French scientist Henri Becquerel discovered natural radioactivity. Many scientists of the period were working with cathode rays, and other scientists were gathering evidence on the theory that the atom could be subdivided. Some of the new research showed that certain types of atoms break by themselves. It was Henri Becquerel who discovered this experience while investigating the properties of fluorescent

James Chadwick was born October 20, 1891 in Cheshire, England. He received the Nobel Peace Prize in 1935 for the discovery of the Neutron. He is the son of John Joseph Chadwick and Anne Mary Knowles. Not much is known about his early childhood, except that he came from a poor family at who struggled to get by at many times. Ever since his early childhood he was very smart, at the age of 11 he won the chance to go to the adored Manchester Grammar School. He was sadly unable to attend because his family

Nuclear energy has been used since 1895 to create weapons that could destroy men by the millions. Scientists later transformed this destructive weapon into a new form of usable, renewable energy. Nuclear energy is energy created by harnessing the energy produced by the nuclear reactions that take place inside the nucleus of the Uranium Isotope 235, ("Nuclear Energy"). Nuclear energy is one attempt to decrease the rate at which nonrenewable fossil fuels are being consumed. Some believe nuclear

and again graduated first in her class. She also earned a degree in mathematics in 1894. Marie married Pierre Curie in the summer of 1895. They met at the Municipal School of Industrial Physics and Chemistry. Together, they studied deeper into radioactivity.

protective envelope. And so his frail wife set about her work, handling tons of minerals’ she noted that another substance, thorium, was "radioactive", a term she herself had coined. Together, they demonstrated in a major discovery that radioactivity was not the result of a chemical reaction but a property of the element or, more specifically, of the atom. Marie then studied pitchblende, a uranic mineral in which she measured a much more intense activity than is present in uranium alone. She

Madame Curie, as the scientist is venerably called, was a true pioneer of her time. Growing up amidst political turmoil and sexual discrimination she was able to persevere with austere determination to make breakthrough scientific findings, while also fighting for humanitarian betterment. In a long list of renowned female scientists Madam Curie stands at the top of the list not only for her findings, but also for her efforts to aid those with the worst afflictions; she is long remembered as a pioneer

dioxide and other emissions, radioactivity, solid waste, and accidents. Radioactivity was noted indicating coal plants release 100 times more radiation than nuclear power plants because of the natural ingredients already in the coal. Results/Outcome The use of nuclear power plants is a more efficient energy source compared to coal power plants. Coal has high emissions of greenhouse gases, especially SO2 which leads to acid rain formation, smog, health impairments, radioactivity and climate change. Nuclear

Due to diverse composition of the wastewater, which can be high concentrations of volatile organic compounds, chemicals, and materials of radioactivity. (Chameides, 2011) This diverse composition of wastewater can disrupt the natural operation of municipal treatment plants by inhibiting biological treatment. Additionally, the wastewater may facilitate the formation of harmful disinfection by products

words are very relevant to the contributions she did to today’s society. Marie was very persistent and dedicated when it came to her work that she even risked her health to pursue her studies. She was one of the first scientists to work with radioactivity and she, along with her husband, discovered two elements of the periodic table, polonium and radium. Marie went through a couple obstacles but was able to complete her studies and pursue her dreams, making a big impact. Marie Curie changed her
