Features and Specifications

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.
  • No nuclear disposal requirements.
  • No additional security requirements for nuclear equipment.
  • No additional safety equipment for laboratory staff.

Direct Replacement for Gamma Irradiator

U.S. Government recognized as a safe and direct alternative for radioactive isotope (gamma) source irradiators.

RS 1800·Q One Day Plug & Play Installation

The RS 1800·Q does not need an external water connection to the facility – providing improved workflow efficiency with flexible equipment placement throughout the facility.

Instrument Portability

Mounted on sturdy caster wheels for convenient portability improves sample workflow efficiency, allowing for the placement of the RS 1800·Q throughout the facility.

Self-Contained Cabinet

All Rad Source irradiators are manufactured as cabinet x-ray devices and conform to the radiation safety guidelines in US CFR 21 1020.41.

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.


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.
