From the stability standpoint, the alpha particle has very stable configurations and plays an important role in reducing the heavy weight of some radioactive nuclei transforming them into less excited or ground state. The position of those radionuclides on the N/Z diagram determines its mode of 1 Basic Radiation Physics 19 235 U 92 231 Th 90 Mass Number A 227 Ac 89 223 Fr 87 219 At 85 215 Bi 83 211 Pb 82 211 Bi 83 215 Po 84 231 Pa 91 227 Th 90 223 Ra 88 219 Rn 86 215 At 85 211 Po 84 207 TI 81 a Decay b - Decay 207 Pb Stable 82 Atomic Number Z Fig.
The probability of this interaction decreases with increasing energy of the incident photon, but increases with increasing atomic number of the absorber. 19) Compton scattering is an inelastic collision between gamma ray and valence electron of an atom whose binding energy is much less than gamma ray energy. It is the most prevailing interaction of gamma ray with soft tissue in energy range used for diagnostic purposes. 19. 2). The probability of Compton scattering increases linearly with atomic number of absorber material.
6 summarizes the physical properties of some crystals used in PET imaging scanners. 56 220 1 Basic Radiation Physics are accelerated, they collide with electrodes in the tube (known as dynodes) releasing additional electrons. This increased electron flux is then further accelerated to collide with succeeding electrodes, causing a large multiplication (by a factor of 105 or more) of the electron flux from its initial value at the photocathode surface. Finally, the amplified charge burst arrives at the output electrode (the anode) of the tube.
