Knowledge Hub · Saxsons Mobile Barrier
A mobile barrier rolls into position in minutes vs the months of a permanent structural-shielding wall. The hydraulic-jack height-adjustable variant tracks the operator eye-line; four lead-glass viewing-window formats cover different line-of-sight needs. ALARA principles + NCRP 147 framework apply to mobile shielding as much as to permanent walls.
Mobile vs permanent shielding
A permanent wall is committed at facility build — concrete + lead + drywall, ~ 6 months lead-time, ~ ₹15–30 lakh per wall. A mobile barrier ships in days, rolls into position, and lets the radiopharmacy adapt the workflow without re-planning the room. Mobile is the answer when the dispense / inject / therapy workflow evolves OR when a temporary therapy site needs shielding TODAY. Permanent is right only when the layout is locked.

Height-adjustable hydraulic-jack
A fixed-height barrier forces the operator to lean / crouch to use the lead-glass viewing window — the dispense workflow becomes a posture problem across a 100-shift year. The hydraulic-jack height-adjustable variant lets the lead-glass window track the operator eye-line as they move between seated and standing dispense positions. Same Pb tier, better workflow ergonomics, lower cumulative musculoskeletal load.
Lead-glass viewing-window format
The Saxsons range offers four lead-glass formats — 8″×4″×4″ (narrow line-of-sight, e.g. injector cart), 8″×8″×4″ (standard dispense bench), 12.5″×8″×8 mm (wide low-profile for full-bench viewing) and 36″×36″×10 mm (oversized full-field room divider). Lead-glass density × thickness gives the Pb-equivalent; pick the window per the line-of-sight requirement, not just the wall tier.

ALARA + NCRP 147 framework
ALARA = As Low As Reasonably Achievable. The three primary ALARA principles — TIME, DISTANCE and SHIELDING — stack multiplicatively. A mobile barrier delivers SHIELDING (Pb wall + lead-glass), supports DISTANCE (positioned per the workflow), and reduces TIME (operator does not need to step away during a dispense event). NCRP 147 is the structural-shielding-design framework that mobile barriers complement — not replace.
Moly Assay Canister + injector cart
The 7.2 mm Pb Moly Assay Canister (RPMBT-17-7.2-30-S-0) carries the Mo-99 / Tc-99m generator eluate breakthrough-test sample to the MUCHA MCA workflow — Eur.Ph. monograph compliance. The 15 mm Pb injector cart (RPMB-27-65-MS-10-N-S-0) is the mobile theranostic patient-side workstation that ferries the dispensed Lu-177 dose to the chair. Both extend the mobile-barrier range beyond the bench-side shielding application.
