The instrument used is normally referred to as a whole body counter. This must not be confused with a "whole body monitor" which used for personnel exit monitoring, which is the term used in radiation protection for checking for external contamination of a whole body of a person leaving a radioactive contamination controlled area. [1]
Internal dose monitoring of the radionuclides which emit radiation which can penetrate out of the body. For example X-rays, gamma rays of sufficient energy. It can be measured by devices such as a whole body counter. A whole body counter [5] has a low background arrangement with counting systems NaI(Tl) detectors for high energy photon detection
The phantom, which contains a known amount of radioactivity can be used to calibrate the whole body counter by relating the observed response to the known amount of radioactivity. As different radioactive materials emit different energies of gamma photons, the calibration has to be repeated to cover the expected energy range: usually 120 to ...
The 21 grams experiment refers to a study published in 1907 by Duncan MacDougall, a physician from Haverhill, Massachusetts.MacDougall hypothesized that souls have physical weight, and attempted to measure the mass lost by a human when the soul departed the body.

A simple crane. A counterweight is a weight that, by applying an opposite force, provides balance and stability of a mechanical system. [1] The purpose of a counterweight is to make lifting the load faster and more efficient, which saves energy and causes less wear and tear on the lifting machine.
The Albert Hall was Canberra's first performing arts venue, opened in 1928. It was the original performance venue for theatre groups such as the Canberra Repertory Society. [119] There are numerous bars and nightclubs which also offer live entertainment, particularly concentrated in the areas of Dickson, Kingston and the city. [120]
