Fluke 481 Radiation Measurement in Bangladesh

Radiation measurement is crucial in many sectors such as medical imaging, industrial inspection, research laboratories, nuclear facilities, and environmental monitoring. Accurate detection and measurement help protect people, equipment, and the environment from harmful exposure.

The Fluke 481 Radiation Survey Meter is a portable ionizing radiation measurement device designed to measure X-ray and gamma radiation. In Bangladesh, it is widely suitable for hospitals, NDT (non-destructive testing) service providers, power and manufacturing industries, and safety officers who need a dependable tool for routine radiation surveys and safety checks.

Pico Labs Limited is a reliable technology provider in Bangladesh where you can explore a wide range of Biomedical Test Equipment at the best price. From hospitals and clinics to diagnostic centers and biomedical engineering departments, you can find professional analyzers, simulators, and test tools for accurate performance checking of medical devices like infusion pumps, defibrillators, patient monitors, incubators, and ventilators.

Why Radiation Measurement Matters in Bangladesh

In Bangladesh, use of X-ray, CT, industrial radiography, and other radiation-emitting equipment is increasing. Proper radiation measurement with a device like the Fluke 481 helps:

  • Protect staff in radiology, cath labs, and NDT operations
  • Check shielding effectiveness of walls, doors, and barriers
  • Ensure compliance with regulatory limits
  • Support emergency response to radiation-related incidents

Reliable radiation measurement is therefore essential for both safety and regulatory compliance.
