X-ray Cannabis Decontamination. The Non-Evasive way to Kill 99.9% of Mold, Yeast, Aspergillus, E.Coli and Other Uninvited Microbials.

We help operators pass state microbial testing requirements — without gamma radiation, chemicals, or heat that can damage or alter quality, color, terpenes, and cannabinoids.

Understanding The Real Need for Decontamination

Cannabis frequently fails state microbial testing due to mold, yeast, and pathogens such as Aspergillus — even in well-managed grow operations. When a batch fails, options are limited and time-sensitive. Kimtron’s X-ray cannabis decontamination systems are designed to reduce microbial contamination throughout the entire flower or biomass, helping operators bring failed or at-risk product back into compliance without chemicals, heat, or radioactive sources that can damage terpenes or cannabinoids.

Microbial contamination is one of the most pressing challenges for cannabis cultivators today. With strict state regulations mandating safe microbial levels for human consumption, compliance is non-negotiable. Molds like Aspergillus and yeasts are considered harmful enough that most states have implemented tight standards and limits on what is allowed. In some cases, the limit is "Undetectable." By integrating the Photon Purification 'Kill Step' into our production process, we ensure the highest safety and quality standards, allowing you to deliver clean, compliant cannabis products to market with confidence.

Our systems are engineered specifically for cannabis processing and GMP-compliant decontamination workflows. As cannabis processors move toward pharmaceutical-grade standards, cannabis processing, GMP-compliant decontamination has become essential for passing microbial testing and meeting regulatory expectations. Kimtron’s ionizing-radiation solutions support full GMP documentation, batch traceability, and validated microbial reduction, giving cultivators and manufacturers a proven method to ensure product safety without compromising potency or quality.

Comparison of Cannabis Microbial Decontamination/Remediation Methods & Technologies.

Cannabis microbial Decontamination can be achieved using several different technologies, each with distinct capabilities and limitations. Surface-oriented methods such as UV-C light, cold plasma, ozone, and steam primarily act on the exterior of the flower and may not fully address internal mold or pathogens such as Aspergillus. Radio frequency (RF) systems use electromagnetic energy to interact with moisture within the product, which can result in volumetric warming and microbial reduction but may also affect terpene and cannabinoid profiles if not carefully controlled. Gamma irradiation provides full-batch penetration but relies on radioactive sources and can involve additional regulatory and logistical considerations. X-ray decontamination, by contrast, delivers deep, uniform penetration without radioactive isotopes or chemical residues, helping operators reduce microbial contamination throughout the product while preserving flower integrity and supporting compliance requirements.

Kimtron X-ray systems use electrically generated radiation with no radioactive isotopes. When operated within validated parameters, X-ray decontamination is permitted in most U.S. cannabis markets where remediation is allowed, provided operators follow state reporting and testing requirements.
X-ray has become the industry standard because it's the most effective solution for cannabis decontamination. Here's why and what makes Kimtron's cutting-edge technology uniquely different.

What makes our HiRad Systems so unique?

X-ray technology for cannabis decontamination isn’t exclusive to Kimtron. While we may have been early pioneers, others have since developed X-ray and ionizing radiation systems.

What truly sets our HiRad system apart is how we apply X-rays.

Our patented Uniform Dispersion technology delivers the most homogenous and evenly distributed dose. Unlike other systems, which often need to overdose the product to ensure the most distant areas receive enough photons to deactivate bioburden, our system delivers even homogenous precision where it matters.

Think of it like baking a cake—most systems overbake the outside to cook the center. With our HiRad systems, every "slice" gets perfectly and evenly treated. And to be clear: X-rays don’t burn or heat cannabis. The cake analogy simply illustrates our ability to provide consistent, uniform dosing through all the buds.

We don’t waste time, energy, or photons.

This video of our HiRad 6002 shows the patented Uniform Dispersion process in action—a technology consistent across all our HiRad systems.

As shown in the video, our patented process—rotating the filled container while moving the X-ray emitters from bottom to top—uniquely maintains consistent, targeted dosing throughout the entire biomass.

Our user-friendly Photon Purification™ HiRad systems deliver clean, safe, heat-free, and chemical-free decontamination, targeting mold and microbial pathogens down to the DNA level. CFUs can be reduced to undetectable levels, all while preserving the product’s terpenes, cannabinoids, appearance, aroma, flavor, and texture.

Currently, X-rays are the only technology that can fully and effortlessly penetrate cannabis flower from end to end—eliminating hidden “cave dwellers” and halting microbial replication post-treatment. We can even treat fully packaged products.

Keeping it COOL with our UNIQUE Cool Cabinet Feature.

We know how important it is to keep your cannabis cool. We'll never heat your weed. We get it. Terpenes can begin to break down at temperatures as low as 80 degrees.

Calling on our 30-plus years of experience in harsh and often HOT industrial environments, Kimtron’s exclusive “COOL Process” ensures your product stays COOL during decontamination.

All HiRad systems come with our exclusive closed-loop, ambient temperature WA-12000 X-ray tube cooler. You don't pay extra, and you don't have to supply chilled water.

Frequently Asked Questions

Does X-ray make cannabis radioactive?

No, the process does not make the cannabis product radioactive.

The radiation passes through the product but does not remain in it after treatment

is complete.

Will this affect terpenes or THC?

Cannabinoids: Studies generally indicate that irradiation does not significantly alter THC or CBD content.
Terpenes: Only a barely detectable reduction in certain delicate terpenes due to accelerated evaporation, not X-rays, and no new, harmful components are formed.
Physical Appearance: The process is typically conducted at room temperature and generally does not affect the moisture content or physical appearance of the dried flower.

What is ionizing radiation for cannabis decontamination?

Ionizing radiation (such as gamma rays, electron beams, and X-rays) uses high-energy wavelengths to penetrate cannabis flower and disrupt the DNA of microorganisms, effectively killing them and ensuring the product is safe for consumption, particularly for medical patients with compromised immune systems. This process is used globally for many products, including medical devices, spices, and certain foods.

Is irradiated cannabis safe for consumption?

Yes, regulatory bodies like the U.S. Food and Drug Administration (FDA) and the World Health Organization (WHO) consider irradiated products safe for consumption. However, since the cannabis industry is not federally regulated in the U.S., a patchwork of state-level rules means some consumers and businesses remain cautious due to a lack of long-term, specific studies on inhaled irradiated cannabis.
