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.
Radon Mitigation. Background. Radon is a colorless, odorless radioactive gas that seeps up from the earth. When inhaled, it gives off radioactive particles that can damage the cells that line the lung. Long term exposure to radon can lead to lung cancer.
