Radioactive decay

China which it is then put on the tips of mining drills. In Encyclopedia Britannica in Britannica School, tungsten has five stable isotopes, tungsten-180, tungsten-182, tungsten-183, tungsten-184, and tungsten-186. There is no radioactive isotope in tungsten that decays into anything. It belongs to group VI-B on the periodic table. In Facts on File in Science Online, pure tungsten is used in light bulbs and x-rays, while others are used in the production of extremely hard steel for tools,…

In 1939, a scientist wrote a letter to the President of the United States, Franklin Roosevelt, which would alter the course of history. This scientist was Albert Einstein – after fleeing from Germany, he was concerned with the possibility of the Nazis succeeded in building a weapon never seen before: an atomic bomb. Einstein encouraged a program to research the prospect of nuclear weapons – the Axis powers gaining access to an atomic bomb would present a catastrophic situation to the Allied…

We care about your property’s health and safety. That is why, for the month of January, we would like to bring to light one dangerous element that is found in a lot of homes. Radon. What is Radon? Radon (Rn) is a radioactive gas. It is created when uranium in soil, rock, or water, decays. Since it’s a gas, you cannot spot Radon with the naked eye. However, what makes this gas even more difficult to detect is that it is odorless and tasteless.…

Logarithms For a start, there are some different courses of mathematics in high school and in college. Many students work enough just to pass the course at least with a C. When the time comes to work with logarithms most of the students have a difficult time working with. In some cases, they tend to memorize the rules with not completely understand them. Although, when they have gone through the chapter about logarithms, they feel relieved to be done with, but they are wrong because in…

Required Reading: Prehistoric people: 1. What does the term “Prehistoric People” mean? How has the advancement in the study of such peoples grown and developed over time? Prehistoric people are humans who lived before writing was invented 5.500 years ago. 2. Where (location) and when (date) were the remains of the oldest known hominid found? The remains of the oldest known hominid were discovered in the Djurab Desert in 2001. 3. Which species of Australopithecus is “Lucy”? What is the…

Contrary to the title, the discovery of astatine was anything but a momentary process. Many scientists discovered different astatine isotopes, atoms with the same number of protons but differing numbers of neutrons, but were unable to either reproduce their results or keep the isotope in existence for any useful amount of time. After decades of possible discovery and rediscovery, astatine was officially included in the periodic table of elements with the abbreviation At and an atomic number of…

individual nuclear power reactors. Planned maintenance was being performed on reactors 4, 5 and 6. Reactors 1, 2 and 3 automatically SCRAMed following the earthquake due to input signals received from their Safety System. Initially the remaining decay heat from the nuclear reactors and their spent fuel storage pools was sufficiently maintained by their Emergency Power Generator’s (EPG). However, when the 14m high tsunami breeched the sea walls, reactors 1-5 lost their secondary coolant…

gravity and these same celestial bodies have their own electromagnetic forces and the strong and weak nuclear forces are. Since everything in the universe is made of atoms, there is strong nuclear force everywhere around us. Also, because radioactive material decays over time, the weak nuclear force is important to our safety. The weakest of all four fundamental forces, gravity, was discovered in 1655 by Sir Isaac Newton. One day, Newton was drinking tea and observed an apple falling from a…

harmless. The article was published on November 11 2014. In this article, they talked about a couple of different things. One of the topics they talked about was the Fukushima nuclear disaster that occurred in 2011, and how the radioactive contamination has slowly started to approach the coast of California. The radiation levels were looked over by researches and found out that the radiation does not pose a risk to the people living on the coast. The article as talked about the…

It is found in the Earth’s crust and can be found in small amounts in rocks and soil. Thorium is far more chemically stable and has limited radioactive debris compared to Uranium making it safer and environmentally friendly.Thorium has little negative effects on the environment as well as health concerns. World production of Thorium would exceed 30,000 tonnes per year. This would lead to an increase…
