A typical gamma ray spectrum is shown in figure 3. The number of counts is plotted as a function of channel number for the radioactive isotope 22 Na. There are a few features to notice from this spectrum. 1. 22 Na emits gamma rays of two distinct energies. These appear as lines having some width and are marked along with their energies in the

fat, carbohydrate, and protein as contributors to the total energy intake. 22. NORDIC NUTRITION RECOMMENDATIONS 2012 oils such as rapeseed and flaxseed oils are rich in both A gradual reduction in the intake of sodium expressed in the form of so- LA is metabolised, for example, to γ-linolenic acid (C18:3 n-6),.

22 Na emits gamma rays of two distinct energies. These appear as lines having some width and are marked along with their energies in the Levels of Na 22 below an excitation energy of 3.1 MeV have been investigated through the F 19 (α, nγ)Na 22 and Ne 20 (He 3 , pγ)Na 22 reactions. Gamma-ray spectra from the first reaction were recorded with an 8-cc Ge(Li) detector at 90°, 0°, and 166° to the α beam using CaF 2 targets and α energies between 4.0 and 7.0 MeV. • Many of these nuclides emit gamma rays at many different energies.

Design: Thirty-two nonobese men underwent sequential overfeeding (1 wk at +50% of energy needs), CR (3 wk at -50% of energy needs), and refeeding (2 wk at +50% of energy needs). AT and its determinants were measured together with body composition as assessed with the use of quantitative magnetic resonance, whole-body MRI, isotope dilution, and nitrogen and fluid balances.
