Analog Radiation Detectors

SEI - Radiation Monitor

The Radiation Alert Monitor 4 is a compact, analog radiation detector designed for versatility and reliability. This general-purpose survey meter can detect alpha, beta, gamma, and X-ray radiation across three selectable ranges. With decades of proven performance in the industry, the Monitor 4 has become one of the leading analog radiation detectors available today. Its simple, ergonomic design features a red count light that flashes and an audible beep for each detected count. A quick flick of your thumb allows for an easy battery check and silent operation.

SEI - Radiation Survey Meter

The Monitor 4EC is an energy compensated, ergonomic radiation survey meter capable of detecting alpha, beta, gamma, and x-rays over 3 selectable ranges. A red count light flashes and a beep sounds with each event detected. The Monitor 4EC offers a linear response for gamma and x-rays (above 40 keV).

Radiation Dosimetry

SEI - Sentry Dosimeter & Ratemeter

The Radiation Alert Sentry EC is a personal alarming radiation dosimeter and rate meter, designed to safeguard personnel working in environments with potential X-ray or gamma exposure.

SEI - Alarming Dosimeter

The RAD-60 is a Personal Alarming Radiation Dosimeter. It’s a precise and reliable instrument for ensuring the safety of personnel. Ideally, the RAD-60 is used in stand-alone conditions for everyday radiation monitoring . The RAD-60 can also be switched into System Mode, for the purpose of tracking Personnel Dose records and generating compliance reports.

SEI - Pen Dosimeters

The advanced PENs are direct reading radiation dosimeters. They are rugged, precision instruments with a higher quality and reliability than other dosimeters of its type. They measure and directly read accumulated dose of gamma and x-ray exposure.
