A revolutionary new radiation detector and one-of-a-kind Geiger counter

The International Medcom Onyx is an accurate, functional, reliable and elegant tool for detecting and monitoring nuclear radiation, whether natural radiation from the earth and stars, or from human-created sources. The International Medcom Onyx features a modern, streamlined look and the use of advanced technologies, making it a one-of-a-kind Geiger Counter. It weighs only 7 oz. (200g.) and measures a mere 5.1 X 2.6 X 0.9 in. (72 X 37 X 13 mm.) making it easy to transport. The Onyx is optimized for detecting low-level radiation, but will also reliably detect, record and report radiation at moderately high levels. Despite its compact size, Onyx is capable of detecting alpha, beta and gamma radiation with the same sensitivity as the IMI Inspector Alert™, and like the IMI Inspector Alert™ V2, Onyx is optimized for surface contamination measurements through use of its 2 in. pancake Geiger Mueller tube. It is the new revolutionary radiation detector born from the multinational response to the Fukushima nuclear radiation disaster, employing design and manufacturing expertise from around the globe and made in the USA by IMI.

Providing easy use of a wide variety of functions

The International Medcom Onyx has six button touch sensitive keypad that allows for easy use of a wide variety of functions such as graphic display of data, adjustment of audio chirp, data logging, changing units of measurement and calibration. The Onyx also permits the user to upgrade the software running on the device to the latest version using a simple internet download feature. The version being shipped with the instrument is the most up to date.

Designed to share data through its micro-USB port

Data are easy to read in a variety of formats (milliroentgens per hour, counts per minute, micro Sieverts per hour and total counts) on the 128 X 128 color OLED display that measures 1.88 in. (47.9mm.) diagonally. In addition, Onyx is designed to share data through its micro-USB port. Twitter data are transferred using QR code displayed on the OLED in combination with a smart phone with a QR Code scanner.

How Onyx works

The International Medcom Onyx uses a 2-inch(7.1cm) Pancake Geiger-Mueller tube with a low-density mica window to detect ionizing radiation. The Geiger tube generates a pulse of electrical current each time radiation passes through and causes ionization. Each pulse is electronically detected and registers as a count. Onyx displays this collected data in the mode you choose: Counts Per Minute (CPM), microSieverts per Hour (μSv/hr) or microRoentgens per hour (μR/hr). The number of counts detected by Onyx varies from second to second, due to the random nature of radioactivity, but averaging protocols provide a fairly stable average of that random data .

Applications of Onyx

If you work around radiation sources, Onyx is a good instrument for personal health protection. In normal environments, the instrument can also provide peace of mind, by letting you know if there are any unexpected radiation sources in your environment. If you are documenting contamination or collecting data for the Safecast Global Network or other networks, you may share the data you collect.

Other applications of Onyx

• Documenting the effectiveness of decontamination and safety programs.
• Sharing radiation measurements with a global mapping system developed by Safecast.
• Monitoring possible radiation exposure while working around radionuclides or in contaminated environments.
• Alerting the user with an audible indicator if radiation goes above a user pre-set Alert level.
• Detecting noble gases and low energy radionuclides.
• Continuous logging of radiation levels
