Consider the source-scatterer-detector configuration of Figure 1. The 22Na source of annihilation radiation is collimated by the Pb cylinder, so that the two quanta emitted up and down may scatter at A1 and A2 into detectors D1 and D2, respectively, with q = 90 .

Therefore, we measured the shielding effect of a clinical X-ray protector and lead glass against annihilation radiation and gamma rays of (99m)Tc. We then calculated the shielding effect of a 0.25 mm lead protector, 1 mm lead, and lead glass using the EGS4 (Electron Gamma Shower Version 4) code.

These were the first maps of galactic positron annihilation radiation. That dataset has been augmented with additional data, both recent and archival, and re-analyzed to improve the spectral fitting.

The use of this dataset to map the galactic distribution of positron annihilation radiation is presented elsewhere at this meeting, This poster concentrates upon the various quantitative analyses that have been performed using the data.

The positron- electron overlap is maximal at points A and B where annihilation is most likely to occur. ... All annihilation events must lie along the horizontal line, seeing that they have an energy sum of 2mc2. The projection onto the momentum axis gives the desired Doppler broadened spectra N(kx).

Doppler broadened spectra of positron annihilation in an aluminium crystal were measured for 59 different temperatures from 298 to 897K. The instrumental response function was unfolded from observed annihilation spectra and intrinsic distributions were obtained.
