Next-Generation Professional Electronic Radon Monitor
The all-new RAD8: rugged and sensitive
The Durridge RAD8 reimagines scientific-quality electronic radon monitors with complete top-to-bottom upgrades in comparison to the venerable RAD7. With its cutting-edge features and optimisations for outdoor use, RAD8 revolutionises radon/thoron monitoring in the field and the lab.
Built for harsh environments
An environment-proof, super portable design with long battery life and IP67 water/dust resistance (even when the lid is open) means you can use RAD8 conveniently and worry-free whether you work near water, on rugged terrain, in a dusty mine, or the gentle confines of a lab.
New patent-pending technology boosts sensitivity 70% higher than RAD7, significantly reducing data uncertainty. RAD8 provides unparalleled access to spectrometry data (including raw sensor counts) so users can analyse and verify measurements in detail.
Superior accuracy
RAD8’s high-resolution alpha spectrometry precisely measures alpha particle energies, enabling it to clearly identify the characteristic alpha energy peaks from the radon and thoron decay chains. This event-by-event species discrimination provides accuracy superior to other technologies such as pulsed ionization chambers and Lucas cells. Radon and thoron are measured independently and simultaneously, without interference – background from the buildup of long-lived decay products that plague other products is rejected from RAD8’s radon/thoron measurements. No matter how long you have owned your RAD8, background will never interfere with your measurements. RAD8 can also recover from high radon concentrations in minutes, rather than hours, to dramatically save time, money, and boost productivity.
Easy-to-operate
The easily navigated, high-visibility colour touchscreen and pushbutton controls let you operate the RAD8 in any conditions, even with gloves on, perfect for measuring Radon in air, water and soil, in homes and buildings, mines and deserts, on the ocean and volcanoes. While the touchscreen provides control over instrument and measurement settings, the RAD8 is delivered with pre-programmed testing protocols to get you up and running quickly. The IATA-compliant rechargeable battery keeps RAD8 running continuously for three days and built-in wireless networking makes data download easier than ever.

| Modes Of Operation |
RAPID mode calculates radon concentration from counts of the polonium-218 alpha peak in the A Window. PRECISE mode calculates radon concentration from counts of polonium-218 and polonium-214 in the A and C windows to achieve higher statistical precision. AUTOMATIC mode switches from Rapid to Precise mode after three hours of continuous measurement to combine the benefits of rapid response and statistical precision. RAD H2O modes work with the Durridge RAD H2O water accessory kit to measure radon concentrations in aerated water samples of specific volumes. |
| Test Protocols |
SNIFF protocol applies the Rapid analysis mode to continuously pumped air samples for spot readings. 1-day and 2-day protocols apply the Automatic analysis mode to air samples pumped with a Standard 40% duty cycle for 24-hr or 48-hr, respectively. Continuous protocol applies the Automatic analysis mode to air samples pumped indefinitely with a Standard 40% duty cycle. Grab protocol applies the Rapid analysis mode for 20-min to air samples that are briefly pumped into the chamber. H2O 40-ml and 250-ml protocols apply the Rapid analysis mode for 20-min to air samples that are briefly pumped into the chamber from Durridge water accessories. |
