1. X-ray Irradiator at UCSF MB

2. Rad Source RS 3400 X-Ray Irradiator

4. Dosimetry
The X-ray Source in the RS 3400 creates a “cloud” of irradiation emitted longitudinally along its axis. The dose of irradiation produced to the Canisters is moderated by the rotation about the X-ray Source. Fig. 7 is illustrative of the distribution of the irradiation to the Canister. The maximum dose will generally be the middle surface of the Canister and the minimum dose will generally be delivered to the central ends of the Canister

5. Available Options
Rad Source has syringe holders for on demand irradiation of syringe aliquots
Rad Source encourage clinical engineering or BioMed to be trained by them in basic servicing of the irradiator.
Rad Scan: Scanner and program to record irradiation of blood products.

8. Items to consider…
Chamber Calibrated film or Thermoluminescent dosimeters (TLD) may be used to perform dosimetry when required to be performed (e.g. X-ray tube is replaced).
Our medical directed had to investigate the acceptability of Chamber Calibrated film.
When will dosimetry be required, post repair ect, the company does list when to perform dosimetry.
Be clear about how you want service reports written. We asked that reports state dosimetry was not required post repair when appropriate.
