Descrizione
The new RAD8 reimagines scientific-quality electronic radon monitors with complete top-to-bottom upgrades in comparison to the venerable RAD7, the instrument which for years has been the industry standard for a variety of applications including air quality testing, health physics, geology, geochemistry, hydrogeology, oceanography, environmental remediation, metrology, and more. With its cutting-edge features and optimizations for outdoor use, RAD8 revolutionizes radon/thoron monitoring in the field and the lab.
Splashing water? Driving rain? Blowing sand? No problem! 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 in the gentle confines of a lab.
New patent-pending technology boosts sensitivity 70% higher than RAD7, significantly reducing data uncertainty. In keeping with the transparent data approach pioneered by RAD7, there is no mystery to how RAD8 measurements are calculated - it’s the opposite of a “black box”. RAD8 provides unparalleled access to spectrometry data (including raw sensor counts) so users can analyze and verify measurements in detail without doubting or questioning "what’s going on inside?"
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. Thus, radon and thoron are measured independently and simultaneously, without interference – background from the buildup of long-lived decay products that plagues other products is rejected from RAD8’s radon/thoron measurements. This means that no matter how long you own your RAD8, background will never interfere with your measurements. In addition, RAD8 can recover from high radon concentrations in minutes, rather than hours, to dramatically save time, money, and boost productivity.
The easily navigated, high-visibility color 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.
RAD8 together with CAPTURE graphing/analysis software provides our customers the ultimate solution for detecting and analyzing their data.

RAD Specifications
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. |
Preset 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. |
