the power used by these lamps are also used in one of the most destructive weapon‚ the hydrogen bomb. This power is tritium‚ an isotope. Isotopes are elements that have different amounts of neutron (Knapp 11). Tritium is an isotope of hydrogen‚ that is used in modern science and there are also health implication through the exposure of tritium. Tritium is an isotope of hydrogen that has mass number 3. It consists of 1 proton and 2 neutrons (the word ‘tri’ in the name means that it has mass number

has a short half life of 6.03 hours which makes storage difficult and transporting impossible. Therefore‚ it is shipped by pharmaceutical companies directly to local market using A 99mTc generator. It is a device that is used to take the metastable isotope 99mTc of technetium from 99Mo which has a half-life of 66 hours which is used to transport over long distances to hospitals. This provides shield for long distance transport to minimize extraction work (Wagner‚

The history of the periodic table reflects over a century of growth in the understanding of chemical properties‚ and culminates with the publication of the first actual periodic table by Dmitri Mendeleev in 1869.[1] While Mendeleev built upon earlier discoveries by such scientists as Antoine-Laurent de Lavoisier and Stanislao Cannizzaro‚ the Russian scientist is generally given sole credit for development of the actualperiodic table itself. The table itself is a visual representation of the periodic

A radioisotope is an isotope of an element with different masses‚ whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha‚ beta‚ and gamma rays (Radioactive Isotopes‚ 2017). Radioisotopes have many different uses in the real world‚ but some of the most beneficial uses are in the field of medicine. Technetium‚ more specifically technetium-99m‚ is used in tens of millions of medical diagnostic procedures annually‚ making it the most commonly

The short-term effect of the radioactive contamination in Fukushima nuclear power disaster A nuclear power disaster can result in terrible radioactive contamination. According to the report of Nuclear Safety and Security Institute‚ radioactive level in the central control room of Unit 1 reactor at the Fukushima Daiichi Station was 1000 times higher than its normal level after the earthquake. The communique reported that the amount of radiation around the gate of the nuclear power plant was increasing

nucleus. Within the nucleus‚ there are protons (+) and neutrons (neutral). To find the number of neutrons in an atom‚ you subtract the atomic mass from the atomic number. Atoms of an element can have different amount of neutrons. These are called Isotopes. 19.3 Unstable Nuclei and Radiation Positively charged protons in nuclei tend to repel one another. In order to make the nuclei stable‚ neutrons are present to dilute the forces of repulsion. It acts like a form of “Nuclear glue.” At short ranges

nuclear power works by radioactivity “Radioisotopes are naturally occurring or synthetic radioactive form of an element. Most radioisotopes are made by bombarding a stable element with neutrons in the core of a nuclear reactor. The radiations given off by radioisotopes are easy to detect. Most natural isotopes of relative atomic mass less than 208 are not radioactive. Those from 210 and up are all radioactive.”(Radioisotope - Hutchinson Encyclopedia) (Radioisotopes image) An example of such radioisotopes
