The Panasonic UD-794 Chemiluminescent Dosimeter (TLD) irradiator also referred to as UD-794 irradiator is a system specifically designed to irradiate dosimeters. The irradiator consists of a Gamma radiation source, shielding material, a channel inside the shield in which to position and irradiate the dosimeter, a mechanism by which to move the dosimeter from its tray, an attenuator, a control panel, and safety interlocks.  Panasonic’s UD-794 Irradiator ensures that components are inside a self-contained unit, constructed of sheet metal panels for safety.

The source used in the UD-794 Dosimeter Irradiator meets special form encapsulation criteria and is permanently mounted inside a shield that surrounds the source. An attenuator allows for the delivery of a low or high dose rate to the dosimeter. The dosimeter channel runs through the shield, allowing exposure to occur. A motor-driven lift mechanism moves the dosimeter into and out of the shield, up the channel. The control panel, integrated with the system computer, shows the system status. With the built-in Auto-changer which can accommodate 10 magazines of 50 TL Badges each, batch irradiation of 500 badges is possible. Offering accurate and effective dosimeter irradiation capabilities, the UD-794 Dosimeter Irradiator is also referred to as a Computerized TLD Irradiator or Panasonic’s UD-794 Irradiator.
