Med Phys 4R06/6R03 Radioisotopes and Radiation Methodology Page 4-1 Chapter 4 Scintillation Detectors Basic principle of the scintillator ScintillatorIonizingradiationLight(visib le, UV)Lightsensor Fig. Principle of the Scintillation Detectors . Scintillates are one of the oldest types of radiation detector because measurements could be made with photographic film. Images could be collected or intensity measurements could be made. Measurements were also made with the human eye observing the brightness of frequency of flashes in the scintillator. Nowadays the light output is converted into voltage pulses that are processed in the same way as pulses from proportional counters, semiconductor Detectors etc. The whole point of Scintillation Detectors is that we want to produce a large light output in the visible range.

Chapter 8 Hyper-Pure Germanium Detector

www.science.mcmaster.ca

In both Si and Ge, the material with highest available purity tends to be p-type, which requires addition of donor atoms for compensation. The alkali metals like Li, Na tend to form interstitial donors in Si and Ge. When one of these donor materials (practically Li) is introduced into Si or Ge, the donor atoms are easily ionized

Fig. 7.4. Effect of an n-type impurity on the lattice structure. When silicon is doped with a pentavalent element, Group V in the periodic table, it becomes an n-type semiconductor. The element (P in this example) has one electron left over after the covalent bonds are formed; this donor electron is donated to the conduction band. Conduction ...

Evaluation of this section of the paper is very difficult for a variety of reasons. Most investigators use methods that have been used earlier by others or have been already published independently as a "methods" paper. Thus the methods section of a paper is often brief and terse. Phrases such as: "the enzyme was measured according to the ...
