Hi All, For those who have and operate Shepherd calibrators/irradiators such as Model 89, 81, 78, etc. or Hopewell units:
1. How often do you do preventive maintenance on your irradiators? Annually, Bi-annually, 5 years, when they're broke? 2. Is it done in-house or by a vendor? Thanks! Rick --- Rick Treinen Radiation Protection Engineer PG&E / DCPP / RP BLDG 104 / 216 / D 805.545.6481 (O) 805.769.8001 (C)
