Radiopharmacist's Notes · Saxsons Dose Cabinet

Four hot lab stations, one cabinet — same radiation-safety programme.

The Dose Cabinet collapses a four-piece hot lab into one workstation. What changes is the procurement footprint, the operator's movement pattern at the dispensing point, and the tidiness of the AERB licensing dossier. What does not change is the radiation-safety programme around it — the SOP, the dose log, the decay-then-release procedure and the AERB site licence all still sit with the radiopharmacy.

Side-by-side: four-station hot lab vs Saxsons Dose Cabinet hot lab

The right column collapses the left column into one capital line and one workspace.

Conventional four-station hot lab

  • Standalone dose calibrator on its own bench
  • Separate L-bench dispensing station with its own lead shielding
  • Standalone sharps decay container in a corner
  • Separate tungsten / lead vial-shield holder near the door
  • Radiopharmacist moves between stations during dose prep
  • Four separate equipment line items in the AERB licensing dossier
  • Four separate maintenance contracts, four spare-parts trails

Integrated

Saxsons Dose Cabinet hot lab

  • Integrated dose calibrator station built into the cabinet
  • Integrated L bench in the same workspace as the calibrator
  • Recessed sharps container shield inside the cabinet itself
  • Tungsten vial shield (PET) on the dispenser; lead variant for SPECT / I-131
  • Radiopharmacist completes dose prep without leaving the cabinet workspace
  • One workstation line item in the AERB dossier with its component spec attached
  • Single Saxsons support contract; India service network for spares

ALARA notes — time, distance, shielding at the dispensing point

  1. Time at source — Integrated geometry reduces the inter-station walking distance the radiopharmacist would otherwise carry while holding a drawn syringe. ICRP 105 frames operator dose as proportional to time spent in the radiation field; less walking, less time.
  2. Distance — The L bench layout puts the operator behind a lead-shielded barrier during draw-up. The integrated calibrator chamber means the operator does not have to carry the source over to a separate measurement station.
  3. Shielding — Tungsten on the PET vial holder is the appropriate material for 511 keV photons (lead at conventional thicknesses is insufficient). Lead is appropriate for SPECT 140 keV and I-131 364 keV. The cabinet ships with the right material for the isotope.

What the cabinet does not change

Useful to be explicit about, because the integration story is often misread as a programme-replacement story:

  • The radiopharmacist still needs AERB-equivalent training and an authorised user designation under the Atomic Energy (Radiation Protection) Rules 2004.
  • The hot lab still needs a documented dispensing SOP and per-patient dose log — the cabinet is the workspace, not the SOP.
  • Decay storage of spent sharps is still a documented decay-then-release process — the cabinet provides the holding shield, the radiopharmacy provides the release log.
  • The room shielding decision (walls, doors, viewing windows) still belongs to the broader hot-lab fit-out; the cabinet's self-shielded design just means the cabinet itself does not drive that decision.
  • AERB site licensing still requires the full programme — RSO, leak-test programme, operator monitoring, waste-management plan, decommissioning provisions.

Scope of this page

The "four-station hot lab" picture in the left column is the typical pattern, not a single specific layout — Indian NM hot labs vary widely in floor area, isotope mix and procurement history. Specific savings (floor area, operator dose, AERB-dossier line items) depend on what is being replaced. The ALARA framing is qualitative — quantitative operator-dose comparisons would require a documented baseline at the specific site. The cabinet supports ALARA at the dispensing point; the broader radiation-safety programme decides whether the site achieves its ALARA target.
