Tritium is a hazardous substance that should only be used by professionals or with professional supervision. However, Tritium undergoes beta decay, which is not as powerful and disables the beta particles from penetrating the skin. It is still not correct to perform experiments without being fully protected. There are still many health risks that are associated with Tritium. Exhaling, drinking and eating substance containing tritium is highly risky for your body. Once tritium has been injected or ingested into the human body, the half-life of the tritium is minimized to 7-14 days which also minimizes the power of the tritium, but still dangerous. A research which took place in Karnataka, India, shows that the half-life is partially based on
The "2nd U.S. Circuit Court of Appeals" held that those business practices that have had a disparate impact effect on the older workers are now considered to be actionable under one national anti-discrimination law (Hamblett, 2004). The case does reaffirm a second Circuit precedent that had been set but which is at odds with what a majority of federal courts have held. The appeals court supported the idea that a layoff plan had been properly brought under the The Age Discrimination in Employment Act of 1967 (ADEA) although the company did not have the intention of discriminating.
In chapter 8 titled "Radium (Ra)" of The Poisoner's Handbook by Deborah Blum, the most interesting story developed within this chapter was the death of dial workers at Orange, New Jersey after been exposed to radium every day. It was interesting due to the fact that radium was used everywhere in the community and was never thought it could harm anyone. Radium was a super element that was used everywhere, but its continuous use unmasked its fatal habits. As it was stated in the text, "Radiant health, the ads proclaimed-beautiful skin, endless vigor, and eternal health—ingesting radium seemed the next best thing to drinking sunlight." (Blum 179). People were accepting radium as a natural gold element but they haven't realized constant contact
Alcoholism is as prevalent in my family, as blood is in our veins. When previously asked to observe 12-step groups, I ritualistically flocked to Alcoholics Anonymous, without consideration of the possibility that other groups had any potential to make an impact on me. I always pride myself in my ability to identify as an individual that is not ensnared in alcoholism, but unfortunately am an individual that was highly tormented by alcoholism. Through observation of the group and how it processed, as well as identifying how I felt as a new attendee, I was able to understand why self-help, support groups are so vital for individuals in recovery. I finally realized, I too am in recovery.
Approximately four babies are born every second of the day in the world, that means that means that there are roughly 345,600 people that have the exact same birthday, including the same birth year. That makes you wonder, what the chances are that a pair of people in a room have the same birthday. With the application of the birthday paradox, also known as the birthday problem, these “chances” can be approximated.
the h-bomb was was made in 1951. Its also called the hydrogen bomb. the united states detonate the first thermonuclear weapon. the hydrogen bomb on eniwetok atoll in the pacific. the test gave the united states a short lived advantage in the nuclear arms race with the soviet union. following the successful soviet detonation of an atomic device in september 1949 the united states accelerated its program to develop the next stage in atomic weaponry.popularly know as the hydrogen bomb this new weapon was approximately 1000 times more powerful than conventional nuclear devices. opponents of development of the hydrogen bomb included j. robert oppenheimer. one of the fathers of the atomic bomb. He and others argued that little would be accomplished except the speeding of the arms race, since it assumed that the soviets would quickly follow suits. the opponents were
Floridium, also known as Fd, is a new element with currently the highest atomic number of 173 and a mass of 486.9 g. Floridium is a part of the P-block and a superactinide , falling right after Neodymium (Nd). It is also highly nonpolar with Neodymium. Because it is a p orbital, it has a dumbbell shaped orbital with three possible orientations. In addition, it has an orange-brown color, is ductile and malleable, and has a boiling point of -57.8 Celsius. The element is quite rare, only found in the Southeast United States. As of 2016, Floridium has been recognized by scientists as an element.
Germanium has 32 protons and 41 neutrons in the nucleus of each of its atoms. Between it’s 4 energy levels it has 32 electrons. 2 in the first, 8 in the second, 18 in the third and 4 in the last energy level. The 4 electrons in the last level are called valence electrons. Valence electrons are the number of electrons the atom must gain/loose to have a full outer shell. An atom’s outer shell is the energy level furthest away from the nucleus, each of the other energy levels are sub shells
The X-43A aircraft was a small unpiloted test vehicle with a length of 3.7 m. The vehicle had a lifting body design i.e. the aircraft body could generate a significant amount of lift, instead of being dependent on wings. The weight of the aircraft was approximately 3,000 pounds (about 1,300 kilograms). The X-43A was designed so that it could be fully controlled in high-speed flight, even while it is in the glide phase without any thrust generation. However, the aircraft was not designed for the landing phase. The test vehicles crashed into the Pacific Ocean when the test was over and nothing could be salvaged.
Yttrium is element 39 on the periodic table. Its atomic mass is 88.9059 and the complete electron configuration is 2-8-18-9-2. Although it is a transition metal, located in group 3 on the periodic table, it forms only one ion, with a +3 charge. Yttrium was discovered by Johan Gadolin in 1789 and is an iron gray color.
Niobium, an element a confused early past. It was named after the Greek mythological figure of Niobe, Niobe was the daughter of Tantalus. The reason Niobium was given this name was because the element itself had remarkably alike chemical properties to the element Tantalum. However it was formerly named Columbium, this was the element’s common name in America. In comparison, the name of Niobium was more frequency in use in Europe. However, such debate over the name of the element came to an end in 1949 at the Conference of the Union of Chemistry in Amsterdam. The verdict was reached and the name of the element officially became Niobium.
Carson uses strontium 90 from nuclear explosions as an example to explain most of the lethal chemical materials released by human beings will eventually go back to our bodies.
Technetium-99m was used in an imaging demonstration in 1964. As a result of its favorable physical and chemical properties, it quickly became one of the most used radioisotopes for nuclear medical procedures (Keevil). This radioisotope can be found in nuclear medicine procedures that involve diagnostics of the heart, kidneys, lungs, liver, spleen, bones, and blood flow (GE Hitachi Nuclear Energy).
Titanium is a strong, light metal. It is as strong as steel and twice as strong as aluminum, but is 45% lighter than steel and only 60% heavier than aluminum. Titanium is not easily corroded by seawater and is one of the elements in the periodic table discovered by the British chemist, Reverend William Gregor in 1791, in Cornwall, Great Britain. Titanium was originally named Gregorite after William Gregor. As he was mining one day he found a residue he couldn't identify and thought it might be a new metal. In 1795 Martin Klaproth an Austrian chemist, verified that Gregor had in fact discovered a new element. Klaproth named the element "titanium", after the Titans from Greek mythology. In 1910, American professor, Matthew Hunter was the first to make pure titanium. (Titanium Industries, Inc. 2016).
As the Royal Society of Chemistry Radioisotopes, are typically bonded to an antibody that binds to cancer cells, and as the isotope decays it “ionises” with the DNA stopping the tumor’s growth short. before, doctors used radioisotope lutetium- 177, that has a half life of six days. This seems promising because its life span allows it to remain still “hot” when it reaches the hospital. However, the problem with this is that because of its half- life, doctors are concerned that it hangs around, causing problems in the future for patients. Luckily,”But now Konstantin Zhernosekov of the Technical University of Munich, Germany, and colleagues have produced a radioisotope that appears even more promising than lutetium-177: terbium.” This is because terbium-161 has a half life of seven days,which emits “two extra low- energy Auger electrons” meaning that compared to lutetium- 171, kills cancer cells faster. This is also promising because terbium 161 emits a low amount of “emits a number of low-energy electrons upon decay, which should make it useful for treating small tumours.” In addition, the study of radioisotopes is ever evolving, as doctors try to find the least harmful tyoe of radioisotope
Technological and accidental hazards can be occur without warning and can be both hazardous material incidents and failures at nuclear power plant. In some cases, victims that have been exposed to harmful chemicals or radiation show little to no symptoms until several years later. There are an increasing number of new substances and chemicals being manufactured which has increased the likelihood of a hazardous material spill or release. This also increases the risk to the environment and to the health and safety of a community.
