High-Quality Radiation Detection Instruments
International Medcom designs and manufactures high quality radiation detection instruments and environmental monitoring systems. These devices have a multiplicity of applications in a wide range of market segments including public health and safety, environmental protection, industrial safety, medicine, physics education, scientific research, and homeland security. 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 community radiation monitoring networks, including those near Three Mile Island and Seabrook, and in perimeter-monitoring security systems for public events in major metropolitan areas throughout the world.

Handheld Geiger Counters


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

Surface Contamination Meters

  • 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
Iospectra® Hawk
  • a monitoring & alarm system that provides power & display for the 1320-AO probe
  • provides siren, flashing light, alarm functions, and relay output for HVAC or security system trigger
→ α = alpha, β = beta, γ = gamma, & χ = x-radiation
