Figure 6.3) are designed specifically for radionuclides that decay by positron emission. Scintillator crystals with high stopping power are utilized, examples are bismuth germanate (BGO) and lutetium orthosilicate (LSO). These…
Safety, position and dose There are two aspects to dose delivery. First, the physical amount of dose and, secondly, is it in the correct position. Both aspects are significant and,…
Table 1.1). The atomic nucleus therefore occupies a minute fraction (10−10 %) of the atomic volume, yet contains more than 99.9% of the atom’s mass. Electrons and protons each carry…
13]. An underdose may well go on for a much longer period of time and the incident at Stoke [14], when an underdose of approximately 20% continued for several years,…
General A commitment to quality control Safety, position and dose Frequency, tolerances and failure trends Measurement and uncertainty Null hypothesis Combining variances and tolerances Setting a tolerance to account for…
6]. In order to understand these layers, we draw a comparison with the postal system (Table 12.1). Table 12.1 The four network layers of the TCP/IP model Layer Network Postal…
