A novel fabrication technique is described based on stacking accurately drilled lead discs to form collimators for rectilinear scanning. This technique has proved successful for the construction of collimators across a wide range of imaging performance.
The application of the 1985 Ionizing Radiations Regulations and Approved Code of Practice to a typical Nuclear Medicine Department has been considered. References to the Regulations are given so that their implications in a given department may be examined. The radiopharmacy, radioisotope dispensary and injection room will need to be Controlled Areas. It will also be necessary to designate Controlled Areas if radiopharmaceuticals are injected in imaging rooms or on wards. Waiting rooms will need to be Controlled Areas. The area around individual patients will, however, not need to be Controlled except for some patients receiving therapeutic doses of 131I for thyrotoxicosis. It should not generally be necessary to designate employees as Classified persons. Major problems in implementing the Regulations are not envisaged in situations where the previous Code of Practice has been followed.

The skin temperature changes associated with menopausal hot flushes have been examined by thermography on a small group of patients. The subjective sensation of heat during a flush seems to be out of proportion to the actual skin temperature increase which was only about 1 degrees C on the face, neck and upper chest during this study. The increased temperature on the cheeks often persisted for several minutes after the symptoms of the flush had subsided, whereas sweating on the forehead produced a more rapid local cooling effect. Sequential temperature changes were portrayed by using an AGA Thermovision Model 680 Medical System with a colour isotherm attachment. This study provided colourful objective evidence that the symptoms of menopausal flushing is associated with an increase of skin temperature which may be monitored by thermography.
