Does the RS 3400 Require External Cooling?

No, the RS 3400 uses a self-contained water-to-air exchange system.

How does the RS 3400 Blood Irradiator differ from other x-ray irradiators?

  • The RS 3400 has a 6 Liter capacity allowing multiple products in the same cycle whether it be whole blood, platelets, or loaded syringes.  Rad Source is the only company with an x-ray emitter that was designed specifically for biological irradiation.
  • The RS 3400 is designed to rotate blood bags around the Quastar™ x-ray emitter using our patented carousel and, therefore, delivers superior uniformity.
  • Unlike other x-ray blood irradiators, the RS 3400 is entirely self-contained and requires no external water supply for tube cooling.
  • The RS 3400 is engineered for extreme reliability as it uses the proven Quastar™ x-ray emitter.
  • The RS 3400 has only ONE x-ray tube and ONE power supply.

How Does the RS 3400 Differ From a CS-137 Gamma Irradiator?

  • The RS 3400 Blood Irradiator uses a Rad Source patented Quastar™ x-ray emitter and therefore contains NO radioactive isotopes.
  • It can be turned on and off, similar to a light bulb.
  • As a result, there are no Nuclear Site License, Homeland Security issues, or room shielding requirements.

How is Ionizing Radiation 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?

  • Ionizing radiation consists of subatomic particles or electromagnetic waves that are energetic enough to detach electrons from atoms or molecules, ionizing them.
  • Two of the most common forms of ionizing radiation are gamma rays and x-rays. Both forms of ionizing radiation are almost identical except for their source of origination.

Why is Ionizing Radiation Used?

Because of the penetrating properties of ionizing radiation and their ability to inactivate 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.

Why Use X-ray Versus Gamma-Produced Ionizing Radiation?

  • Gamma ionizing radiation is produced by radioactive sources such as cobalt 60 or cesium 137 and is dangerous, requiring heavy shielding and high levels of security to protect.
  • The unstable material is constantly decaying and cannot be turned off. X-ray ionizing radiation is produced by an x-ray tube; therefore, it can be turned off when not in use, requiring much less shielding. At the end of the unit’s lifecycle, the unit does not have any radioactive source.
  • It does not require the expensive disposal costs associated with radioactive sources that continue to degrade over hundreds of years.
