The new PET “L” type benchtop breastplate is designed to create a pro- tected working area in front of the Dose Milking unit and for the safe use of 511 keV isotopes. The front wall and floor of the unit are con- structed with lead shielding within the steel structure. The lead-glass window offers the highest level of protection and unlimited viewing space. In addition, Lead Glass is protected by window glass against scratches and scrapes.
