Lead shielding for a large plastic detector panel is far larger than that required to shield a Nal crystal, but the plastic panels are less likely to be disrupted by thermal or physical shock than are the crystal diodes. Transmission X-ray inspection, simultaneously with radiation detection, reveals the presence of lead shielding which may be used to foil radiation sensors. However, there are some uses of heavy metals for which there is no alternative yet, such as lead shielding around x-ray film and lead solder in printed circuit boards. |
