10.2.2.2. Open installations

| top | pdf |

An open installation because of operational requirements cannot have many of the safeguards suggested in Subsection 10.2.2.1[link]. It is essential that extreme caution be exerted by the operators of such installations. They should bear in mind the following facts:

  • (i) almost all radiation injuries in X-ray diffraction laboratories are to the fingers of the operators and occur when setting up monochromators close to the radiation source. Necrosis of the skin occurs within seconds under these circumstances.

  • (ii) The beams scattered from single crystals are highly directional and very intense. Finding and monitoring these beams is usually difficult, and normal radiation monitors tend to underestimate the dose.
