Geiger Counters • Radiation Monitoring Systems from International Medcom

International Medcom designs and manufactures high quality instruments and systems for detecting nuclear (ionizing) radiation. The Radalert and Inspector Alert are used by many fire departments, police departments, and other emergency response agencies. Our custom-designed environmental monitoring systems are used in the community monitoring networks developed at Three Mile Island in Pennsylvania and near the Seabrook nuclear power plant north of Boston.

Handheld Geiger Counters

General purpose Geiger counters designed for diverse applications including medical, scientific, industrial, safety, environmental, hobbyist, and educational purposes

Surface Contamination Meters

Designed specifically for laboratory, medical, & regulatory compliance applications that require higher sensitivity to α, β, & low-energy γ radiation

Monitoring Systems & Probes

Designed for continuous monitoring of ambient radiation levels & for collection of meteorological & other data

2-inch "pancake-style" Geiger tube provides greater sensitivity & faster response time

Inspector EXP

identical features as Inspector Alert except the Geiger tube is housed in an external probe

Iospectra^® 1320-AO Probe

β, γ, & χ + energy-compensated γ
can be configured to detect α as well
designed for continuous outdoor monitoring in harsh environments
operates with data logger, Iospectra^® Hawk, or computer & Iospectra^® software

Monitoring Systems

The Iospectra^® Hawk is a wall-mount monitoring & alarm system that provides power and display for the 1320-AO probe. It also provides siren, flashing light, alarm functions, and relay output for HVAC or security system trigger.
Our EMS monitoring systems are designed to automatically collect & analyze radiation, meteorological, & other data.
We can customize systems to include, among other features, automatic integration of data into a GIS map.

→ α = alpha, β = beta, γ = gamma, & χ = x-radiation
