University Nuclear Physics Labs
BSI supplies CR-39 nuclear track detectors for undergraduate physics, nuclear engineering, and radiation education labs that need reliable class sets, fast domestic fulfillment, and experiments students can actually see.
CR-39 gives students a physical record of radiation. A charged particle damages the polymer along its path. After etching, that latent damage becomes a visible track under a microscope. That makes CR-39 useful for courses where students need more than a black-box counter reading.
Common teaching labs include alpha particle exposure, track counting, radon measurement exercises, neutron detection demonstrations with boron-coated chips, and comparisons between exposure time, etch time, and observed track density. The detector is passive, inexpensive, and easy to distribute across a class.
BSI can provide standard chips for small lab sections or bulk class sets for repeat use across a semester. Standard chip formats include 1 cm x 2 cm and 1 square inch. Custom sizing is available when a lab fixture, source geometry, or microscope stage requires a specific detector shape.
The most useful request includes the number of students, the number of lab sections, the intended source or exposure method, whether the detectors need boron coating, and whether the class will do its own etching and microscopy. That lets BSI recommend chip quantity, format, and handling guidance instead of quoting a generic part number.
Academic labs run on fixed calendars. If detectors arrive late, the experiment may miss the teaching window. BSI's domestic supply chain helps instructors plan around semester timing, repeat sections, replacement chips, and custom detector sizes without waiting on overseas procurement cycles.
Data For Decisions
| Teaching need | BSI CR-39 fit | Notes |
|---|---|---|
| Alpha particle lab | Standard CR-39 chips | Good for track visibility and exposure-time studies |
| Radon exercise | Passive detector exposure | Supports classroom environmental radiation modules |
| Neutron demo | Boron-coated CR-39 | Thermal and epithermal neutron sensitivity |
| Class set | Bulk ordering | Academic pricing available on request |
Direct Answers
The detector itself is a passive plastic chip. Safety controls depend on the radiation source and etching workflow used by the teaching lab.
Yes. BSI can discuss custom sizing, bulk quantities, and class-set packaging for university labs.
Yes. Many labs can use optical microscopy for teaching-level exercises. For advanced projects, BSI can also discuss SEM large-area mapping and AI-assisted analysis.
