The Performance is unmatched.
The RS 1800·Q is driven by patented QUASTAR® x-ray and RADPlus™ technology to provide the highest dose rate and best dose uniformity in the industry for the inactivation of cells.
- RS 1800·Q – 7 Gy / Min.
- RS 1800·Q4 – 12 -13 Gy / Min.

Available Components & Accessories
High X-Ray Output – High Throughput
Produces a high x-ray output, and has a large field, providing advantageous configurations for high throughput and dose rate.
Better Uniformity
Due to the larger field with no need to collimate the beam, a better uniformity can be achieved compared to standard imaging tube x-ray technology.
Beam Hardness – Built-in Filtration
Quastar has filtration built into the design of the x-ray emitter – designed to attenuate weaker non-penetrating x-rays.
Power Efficiency – Increased Life Span
The Quastar emitter runs at less than maximum power which increases lifetime of 7 years or more – up to 2.5X longer than the standard imaging x-ray tube x-ray.
Repairable Energy Source Design – Manageable Cost of Ownership
Unlike traditional imaging x-ray sources that require full replacement, the Quastar emitter is engineered to be repairable and last up to 7 years. Only Quastar can achieve superior dose uniformity resulting in lower run times.
No Radioactive Source – Lower Cost of Ownership (RS 1800)
- Meets safety requirements specified in Fed. Reg. 21 CFR 1020.40.
- No Nuclear Regulatory Commission (NRC) License is required.

FAQs
HOW IS IONIZING GENERATED?
Ionizing radiation comes from radioactive sources such as cobalt 60 and cesium 137 and non-radioactive sources such as X-ray tubes. Radioactive sources are unstable materials where gamma rays originate from the nucleus. X-rays originate in the electron fields surrounding the nucleus or are machine-produced.
WHAT IS IONIZING RADIATION USED FOR?
Because of the penetrating properties of ionizing radiation and their ability to kill microorganisms, ionizing radiation is used to sterilize or reduce the microbial load of many different types of products such as medical devices, packaging, cosmetics, foods, and agricultural products. It is also used to alter the properties of many different polymers through recombination, cross-linkage, and cross scission.
