Sterilization & Sterile Barrier Manufacturing worked example

Gamma Dose Cost at 99% dose-mapped loading: a worked example in sterilization & sterile barrier manufacturing

What does the result look like when dose-mapped loading reaches 99%? The full calculation is worked below with real intermediate numbers. A sterilization buyer comparing gamma contract pricing for a product family at a target 25 kGy dose.

The inputs for this scenario

  • Pallets Irradiated: 60 pallets (unchanged)
  • Irradiation Rate per Pallet: 320 $/pallet (unchanged)
  • Dose-Mapped Loading: 99 % (raised for this scenario; the documented default is 88)
  • Dosimetry & Release Fee: 750 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total gamma dose cost = pallets irradiated x rate per pallet x dose-mapped loading + dosimetry & release fee) to the inputs above produces each figure below.
  • At this operating point the engine returns 19,758 $ for total gamma dose cost, the number this scenario is built around.
  • At this operating point the engine returns 329 $ / piece for gamma dose cost per unit.
  • At this operating point the engine returns 19,008 $ for variable gamma dose cost.
  • At this operating point the engine returns 750 $ for fixed gamma dose cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where dose-mapped loading sits at 88% and the headline result is 17,646 $, this scenario comes in 11.97% above the baseline at 19,758 $.
  • A figure at this level is achievable when dose-mapped loading is genuinely sustained, not just peaked for a shift. It models list pricing structure, not volume discounts, tote versus pallet handling, expedite premiums, or dose-limited product that fails at higher packing densities.

Results at a glance

  • Total gamma dose cost: 19,758 $ (headline result)
  • Gamma dose cost per unit: 329 $ / piece
  • Variable gamma dose cost: 19,008 $
  • Fixed gamma dose cost adder: 750 $
