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.
There are two different types of radon tests: 1  Passive tests: A passive device does not require electricity or power to operate. 2  It has the advantage of being very inexpensive, but it does not provide an indication of changes during the test period.3  It usually requires laboratory analysis to determine the radon level.hat is Radon. Radon is a radioactive, colorless, odorless, and tasteless gas. It is formed as natural deposits of uranium throughout the earthâs crust decay. As radon decay products are inhaled, they can alter the cells in the lungs.
