Blood Throughput Calculator Tool

Compare current cesium-based machine to X-ray.

This web tool provides throughput comparisons based on user input for their current cesium-based machine and data from known FDA approved X-ray devices. The tool is intended to help determine whether switching to an X-ray machine could meet users needs.

The Blood Throughput Calculator Tool was prepared in cooperation with the U.S. Department of Energy (DOE) National Nuclear Security Administration (NNSA) Office of Radiological Security (ORS). For more information on ORS programs: Click here

Site operation procedures for the current cesium-based irradiator allow:		600mL bags max. per cycle
Average cycle time for the current cesium-based irradiator (25 Gy center dose):		minutes
On average, my site irradiates:		600 mL bags
Per:	day week month

Results Comparison: Cs-137 and X-ray Irradiators. See Calculation Assumptions

Cs-137 Irradiator	Average X-ray Irradiator
Throughput of 600mL blood bags/ week.	Throughput of 600mL blood bags/ week. Max throughput of 600mL blood bags/ week. This is more/less than your current cesium-based irradiator. Throughput result uses the same capacity (bags per cycle) as the cesium-based irradiator. Maximum result uses the maximum capacity available for the average x-ray irradiator. Both results assume the same number of operating hours as the current cesium-based device. Both results use the irradiation time of an average x-ray irradiator.
Forecasted Time Devoted to Irradiation: min/ week in 1 year min/ week in 3 years min/ week in 5 years Allowing for the decay of Cs-137 in the user’s device.	Forecasted Time Savings using X‑ray: min/ week in 1 year min/ week in 3 years min/ week in 5 years Expected time savings in each subsequent year assume that the average x-ray irradiation cycle time does not increase over time, and the current product irradiation needs remain constant. Based on Cs-137 decay.
