Counts per minute (abbreviated to cpm) is a measure of the detection rate of ionization events per minute. Counts are only manifested in the reading of the measuring instrument, and are not an absolute measure of the strength of the source of radiation. Whilst an instrument will display a rate of cpm, it does not have to detect counts for one ...
Civilian Public Service firefighting crew at Snowline Camp near Camino, California, 1945. The Civilian Public Service ( CPS) was a program of the United States government that provided conscientious objectors with an alternative to military service during World War II.

The People's Republic of China conducted CHIC-4 with a Dongfeng-2 rocket launch on October 25, 1966. The warhead exploded with a yield of 12 kt.
Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. [1] It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. [1] As of 2007, "medical radiation exposure" was defined by the International Commission on Radiological Protection as ...
United States Air Force NASA. Number built. 3. The North American X-15 is a hypersonic rocket-powered aircraft operated by the United States Air Force and the National Aeronautics and Space Administration (NASA) as part of the X-plane series of experimental aircraft. The X-15 set speed and altitude records in the 1960s, crossing the edge of ...
The blood plasma is then poured or drawn off. [5] For point-of-care testing applications, plasma can be extracted from whole blood via filtration [6] or via agglutination [7] to allow for rapid testing of specific biomarkers. Blood plasma has a density of approximately 1,025 kg/m 3 (1.025 g/ml). [8] Blood serum is blood plasma without clotting ...
Hypovolemia, also known as volume depletion or volume contraction, is a state of abnormally low extracellular fluid in the body. [1] This may be due to either a loss of both salt and water or a decrease in blood volume. [2] [3] Hypovolemia refers to the loss of extracellular fluid and should not be confused with dehydration.
