One job, four ways to do it.

Find the source, identify the isotope, and decide what to do next. The line spans handheld identifiers, human-portable and vehicle search systems, personal and survey instruments, and laboratory-grade analyzers. Pick the form factor your mission needs.

Berkeley Nucleonics SAM handheld radioisotope identifier

Handheld Identifiers (RIID)

Point, measure, identify

Single-hand radioisotope identifiers that classify a source into ANSI categories in the field. NaI, CeBr3, and lanthanum detectors, gamma and neutron channels, and a modern interface that guides the operator from alarm to answer.

Berkeley Nucleonics SAMpack 120 radiation detection backpack

Search Systems

Cover ground, find the source

Human-portable and vehicle-mounted detection for wide-area search and screening. Large NaI volumes, GPS mapping, and wireless links turn a person on foot or a moving vehicle into a continuous radiation survey.

Berkeley Nucleonics Model 951 personal radiation detector

Personal & Survey

On the belt, in the hand

Pocket detectors, dosimeters, and survey meters for everyday radiation safety. Personal radiation detectors alert and locate, survey meters read alpha through gamma, and a hybrid wand pairs radiation with metal detection.

Berkeley Nucleonics Model 970 MCA multichannel analyzer

Analyzers & Monitoring

Lab-grade spectroscopy

Multichannel analyzers and a fixed monitoring system for spectroscopy and continuous watch. Pair the MCA with a NaI, CsI, CeBr, or LaBr detector, run field analysis software, or stand up an area monitor with plastic and NaI detection.

Across the line

Built to identify, not just alarm.

NaI / LaBr3 / CeBr3

Detector materials

Scintillators span NaI, CeBr3, LaBr, LBC, CsI, plastic, and Geiger-Mueller tubes, matched to the resolution and ruggedness each role needs.

Gamma + Neutron

Detection modes

Gamma identification across the line, with neutron detection on the SAM identifiers, search systems, and the PM1703GNA-II for SNM sensitivity.

ANSI categories

Isotope libraries

On-board libraries sort sources into ANSI, SNM, IND, MED, and NORM categories, with custom and ITRAP options on select models.

ANSI N42

Standards posture

The identifiers are designed against the ANSI N42 family of radiation detection standards. Specific model certifications: verify against the published datasheet.

Reachback

Adjudication support

Spectra and results export for reachback and adjudication workflows, including RadResponder-style sharing for secondary review.

Software / MCA

Spectroscopy tools

SNAP-MCA and Spectroscopy Field Analysis software drive the Model 970 and Model 971 for laboratory-grade spectral work.
