Conventional sterilization processing uses environmentally unfriendly radioisotopes [Cobalt-60] or Ethylene Oxide [EtO] to neutralize pathogens in products [medical devices, lab supplies, food, etc.]. Radiation sterilization's modern, safe, clean, and more expedient method is electron beam [E-beam]. Similar to machines used in radiotherapy to treat cancer in humans, E-beam uses a linear accelerator at a fixed energy and at a significantly higher power to provide extreme dose penetration and production throughput.
Products are configured on an irradiation carrier; these carriers are themselves processed equidistant from the accelerator[s] for each and every pass through the system for quality purposes. All carriers proceed through the scanning electron beams at a predefined speed in order to deliver a validated dose. An independently powered processing conveyor is used to precisely control said product movement though the beams.
Nutek Bravo's control system continuously monitors the key parameters of the E-beam and material handling subsystems to ensure that all processes are within operational limits. Any out-of-limit condition will initiate a coordinated, instantaneous shutdown of the E-beam and material handling subsystems to protect products from undue dosing.
Dosimetry is used to verify that the doses delivered to processed products are within specification. This, along with parametric outputs from the processing system, are monitored and recorded to create a well-defined audit trail.
