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.
Confidence votes 77.6K. Radon-222 is one of the isotopes or the inert gas radon. It is the longest-lived occurring one, and it appears as a daughter of the radioactive decay of radium (226Ra).It is radioactive (as are all of radon's isotopes), and, as such presents a hazard to people.ranium is the source of radium, and from radium we see radon. Uranium is present in the ground in a number of types of rock, so radon could appear in soil samples, in ground water, or in the lower internal spaces in buildings (because is seeps in).
