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.

Body roundness index (BRI) is a calculated geometric index used to quantify an aspect of a person's individual body shape. Based on the principle of body eccentricity, it provides a rapid visual and anthropometric tool for health evaluation. [1] Introduced in 2013, the BRI calculation can be used to estimate total and visceral body fat.
RFM is a simple anthropometric procedure that is claimed to be more convenient than body fat percentage and more accurate than the traditional body mass index (BMI). The ratio of the patient's height and waist measurement, both in meters, is multiplied by 20 before being subtracted from a number (shown in bold below) that adjusts for ...
BMI. BMI measures a person’s weight compared to their height. It’s a simple division equation. Since it’s such a quick and easy way to get a rough idea of whether you have a healthy weight ...
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
Clarke noted that at the time of death there is a sudden rise in body temperature as the lungs are no longer cooling blood, causing a subsequent rise in sweating which could easily account for MacDougall's missing 21 grams. Clarke also pointed out that, as dogs do not have sweat glands, they would not lose weight in this manner after death.
In males, mean percentage body fat ranged from 23% at age 16–19 years to 31% at age 60–79 years. In females, mean percentage body fat ranged from 32% at age 8–11 years to 42% at age 60–79 years. But it is important to recognise that women need at least 9% more body fat than men to live a normal healthy life. [2]
