Why pH Measurements Are Important. Chemicals reactions in water are affected by the acidity or alkalinity of the solution. This is important not only in the chemistry lab, but in industry, cooking, and medicine. pH is carefully regulated in human cells and blood. The normal pH range for blood is between 7.35 and 7.45.
The radiation one typically encounters is one of four types: alpha radiation, beta radiation, gamma radiation, and x radiation. Neutron radiation is also encountered in nuclear power plants and high-altitude flight and emitted from some industrial radioactive sources. Alpha Radiation. 2  Alpha radiation is a heavy, very short-range particle and is actually an ejected helium nucleus. 3  Some characteristics of alpha radiation are: 4  Examples of some alpha emitters: radium, radon, uranium, thorium.
1-800-220-3675. Radon is a radioactive gas that comes from the natural radioactive decay of radium, which is a natural decay product of uranium. Scientifically, âradonâ is known to be radon-222, the most abundant isotope of the element radon.s a noble gas, radon is colorless, odorless and chemically inert and cannot be detected by human senses. Also, since radon is not chemically reactive with most materials, it will move freely as a gas. Radon has a radiological half-life of 3.8 days, and can move substantial distances from its point of origin.
