Radon is a health hazard exposure can cause lung cancer. Likewise, the saturated zone of a soil frequently has a higher radon content than the unsaturated zone because of diffusional losses to the atmosphere. Hence, ground water has a higher concentration of 222Rn than surface water, because the radon is continuously produced by radioactive decay of 226 Ra present in rocks. Natural radon concentrations in Earth's atmosphere are so low that radon-rich water in contact with the atmosphere will continually lose radon by volatilization. At standard temperature and pressure radon is a colorless gas, but when it is cooled below its freezing point (202 K −71 ☌ −96 ☏) it has a brilliant phosphorescence which turns yellow as the temperature is lowered, and becomes orange- red at the temperatures air liquefies (below 93 K −180 ☌). Įssentially chemically inert but radioactive, radon is the heaviest noble gas and one of the heaviest gases at room temperature. Radon gas from natural sources can accumulate in buildings and reportedly causes 21,000 lung cancer deaths per year in the United States alone. Radon is a significant contaminant that affects indoor air quality worldwide. The most stable isotope is 222Rn which has a half-life of 3.8 days and is used in radiotherapy. It is one of the heaviest gases and is considered to be a health hazard. Radon is a radioactive noble gas that is formed by the decay of radium. Unfortunately, it has some compatibility issues with Windows 10.Radon ( pronounced /ˈreɪdɒn/) is a chemical element that has the symbol Rn and atomic number 86. Taking all of this into consideration, it becomes clear that Periodic Table Explorer Portable is a useful and complex piece of software, dedicated to people passionate about chemistry, or students eager to learn about it. Moreover, the program includes a calculator, which enables you to convert temperature, find out the molarity from mass and volume, and so on. View biographies of famous people with valuable contributions to chemistryīiographies of all people that have contributed in some way to chemistry are available, along with the atomic structure and radius, electron configuration of all elements, a molecule viewer and pictures of all elements. It is also possible to display all sort of graphs comparing all elements according to basic properties (atomic volume, melting point, symbol etc.), abundance, discovery, hardness, electrical or elastic properties and so on. You can open a window with the periodic table and clicking on an element will bring up a new window which presents all available information about it, including abundance, discovery, density, critical temperature, melting point, uses and hazards. Furthermore, it is accessible to anybody, even people with little to no experience with computers. The interface is quite straightforward and encloses a menu bar, a few shortcut buttons and a panel to display all sort of information. Examine a graph with the color-coded chemical elements Aside from that, you should know the Windows registry and Start menu/screen are not going to suffer any changes due to Periodic Table Explorer Portable. This is the portable version of Periodic Table Explorer and thus, it can be used on any computer you have access to, by simply moving the program files to a portable storage unit and clicking the executable. Explore the periodic table using a portable tool Periodic Table Explorer Portable is a complex software application which helps you analyze the periodic table, as well as view information about important chemists throughout history and other facts.
