The 420 Cannabis Remediation Systems

Pass State Mandated Testing Levels with 99.9% Confidence

Rad Source’s patented Quastar® Photonic Decontamination  technology provides the cannabis industry with the only technology to safely inactivate Mold, Powdery Mildew, Aspergillus, BTGN, Yeast, Salmonella, E. coli, Coliform and other challenging microbes. Our room-temperature process maintains flower integrity w/ nominal to no effect on cannabinoids, THC/CBD, terpenes & moisture. 

Rad Source in Action

Our patented photonic decontamination™
technology is the only remediation solution  that penetrates the entire flower for cannabis decontamination without destroying the flower or chemically modifying it.

Cannabis products provide benefit to both patients who require medical cannabis for treatment and adult-use cannabis users. In both circumstances, cannabis harvesting and processing are regulated by strict quality regulations to ensure the final product does not risk the health of consumers. Harmful mold and bacteria are sources of cannabis contamination that need to be eliminated before it can be sold in dispensaries. 

While other methods to decontaminate cannabis can lead to incomplete inactivation of mold and bacteria and regrowth of them in the final product, our patented Photonic decontamination technology inactivates these contaminants immediately, preventing them from multiplying later on and reaching a level that is a health hazard to consumers.

Peace-of-Mind Microbial Remediation™

Rest Assured, Test Assured

Quastar® Photonic Decontamination™ technology provides a 99.9% confidence level in remediation of mold, powdery mildew, aspergillus, BTGN, Yeast, Salmonella, E. Coli and other challenging microbes.

Flower Integrity Maintained

Photonic decontamination is a room temperature process which results in nominal to zero effect on cannabinoids, THC/CBD, terpenes and moisture.

Highest Flower Penetration

Only Quastar has the power to penetrate the entire flower and inactivate all the microbes that grow both inside and on the surface of the compacted flower.

Features & Benefits

Patented Quastar® Photonic Decontamination™ Technology   

Superior High Quality Photons – Highest Flower Penetration

Produces efficient short light wavelengths that assure 99.9% remediation efficiency rate and the power to penetrate a tightly packed flower to destroy challenging microbials at their DNA level preventing reproduction.

Protects Public Health

Uses the same technology as the FDA has approved for food to reduce dangerous microbes in a biomass. Proven technology in use in Canada and the Netherlands for cannabis.

Repairable Light Source Design - Low Cost of Ownership

The Quastar light is engineered to be repairable and last up to 7 years. Only Quastar can achieve superior dose uniformity resulting in lower run times.

Designed for Life Science, Natural Fit for Cannabis

Quastar is designed to perform as well with Cannabis as it does for Life Science applications. For the cannabis market, it is specifically designed to inactivate microbes at their DNA levels thus inhibiting their ability to reproduce and grow.

Superior Flower Integrity

Photonic Decontamination will not heat the flower, thus causing premature decarboxylation of THC A. Also, unlike chemical and other energy remediation processes, Rad Source’s solution will leave your cannabinoids, terpenes, moisture, and visual quality of your product intact.

Chemical and Residual Free Technology

Photonic Decontamination penetrates the flower with light and will not saturate the surface layers of a flower with disinfectants or other potentially toxic chemicals, nor will photonic decontamination leave any potential residuals.

Helps Prevent the Risk of Secret Shopper

Microbials can continue to grow inside the flower and on the surface even after other remediation technologies. Therefore the photonic decontamination method is the best choice to be able to penetrate the flower.

Hassle-free Onsite Processing

Integrates into existing process – no additional costs associated with outside decontamination facilities. (logistics, inventory, insurance, chain-of-custody, shipping and more.

Physical Appearance and Integrity Maintained

Rad Source’s proprietary carousel technology stabilizes the loaded cannabis canisters and gently moves the flower around the light source to provide unmatched dose uniformity and decontamination without damaging trichromes or other physical characteristics of the product.

Instrument Portability

Models 420 M and 420 Q are mounted on sturdy castor wheels for convenient portability and placement improving product workflow efficiency.

Safe, Clean and Green

Uses efficient short wavelength electromagnetic energy (light) which is safe, clean, and green as nature intended.

Proven Reliability – Earned Trust

For over 20 years and with more than 500 instrument installs in renowned hospitals, universities, government, research and life science institutions worldwide, Rad Source has provided the globe’s leading companies providers with reliable technology solutions and services.
