Domestic Nuclear Track Detectors

American CR-39 Manufacturer

BSI manufactures nuclear-grade CR-39 (PADC) track detectors in the United States for customers who cannot treat detector supply as a generic overseas commodity purchase.

Why does domestic CR-39 manufacturing matter?

For ordinary classroom use, a detector chip may look like a small plastic part. For national labs, defense contractors, and sensitive research programs, the supply chain matters. Domestic manufacturing reduces procurement friction, improves communication, and avoids avoidable uncertainty around foreign sourcing.

Who needs a US CR-39 supplier?

Federal procurement teams, national laboratories, defense contractors, university nuclear engineering programs, and commercial radiation-detection customers may need a US-based supplier for schedule, quality, documentation, or program-security reasons.

What makes BSI credible?

BSI is a Texas Tech University spinout with published peer-reviewed research on CR-39 analysis, including AI-assisted SEM large-area mapping work by D'Amico and collaborators in Nuclear Engineering and Technology in 2025.

What should procurement officers ask for?

Procurement teams should ask about detector dimensions, coating needs, lot size, delivery schedule, documentation, and any program-specific sourcing language. BSI can then respond to the actual procurement constraint instead of treating the request as a generic plastic sheet purchase.

Why not treat CR-39 as a commodity import?

For sensitive measurement programs, detector provenance, lot consistency, communication with the technical team, and lead-time reliability can matter as much as unit price. A domestic source also gives program managers a clearer path for follow-up analysis, custom sizing, and coating questions.

Direct Answers

Common questions

Is BSI claiming every procurement certification?

No. Procurement officers should confirm program-specific clauses directly with BSI. The practical claim is domestic manufacturing and a US-based technical supply chain.

Can BSI support custom detector requirements?

Yes. BSI can discuss chip size, boron coating, bulk orders, and analysis workflows.

Does BSI support federal and defense buyers?

Yes. The page is written for procurement teams that need a US-based technical supplier for nuclear detection projects, national labs, and defense-sensitive programs.

What should be included in a procurement inquiry?

Include quantity, required detector dimensions, coating requirements, target delivery date, documentation needs, and any sourcing clauses that matter to the program. That lets BSI answer procurement reality instead of just quoting a catalog line.

Next Step

Ask BSI for the right configuration.

If your program needs a domestic CR-39 source, contact BSI with quantity, sizing, coating, documentation, and procurement requirements.
