This tool determines the air volume needed from Heat Recovery Ventilators (HRV) to reduce radon concentration to a certain level. Heat Recovery Ventilators (HRV) are very useful as a second phase after Active Soil Depressurization (ASD) has reduced radon to near 4 pCi/L. They can reduce radon through dilution and […]

The Radon-T is the unique fitting specifically designed as the important first step when installing or roughing in a radon and moisture system during new construction. Radon-T by RadonAway Each Radon-T comes with a kit that includes: ➕ Radon-T – Prepares for Reducing Radon in New Construction (RRNC) systems. ➕ […]
RADON IN PILLOLE: WHY CALIBRATE A MEASUREMENT INSTRUMENT? 📽️ In this video, we will answer this common question: 🗯️ Perché tarare uno strumento di misura? Calibration: ✅ calibration has the purpose of defining the metrological characteristics of a measuring instrument; ✅ verifies the accuracy and precision of the instrument […]
The equilibrium equation is a simple formula that defines the relationship between the concentration of radon in the air and the fraction of its decay products that remain suspended in the air. The pie diagram shown below is a useful tool for remembering and manipulating the equation (WL*3700/EF*Rn =1). Equilibrium […]
RADON IN PILLOLE: WHAT IS A “SAFE” LEVEL OF INDOOR RADON GAS? 📽️ In this video, we will answer this common question: The short answer is the “safe” level of radon exposure is no radon at all. Any radon exposure carries some risk. 🗯️So does it mean that we […]
Reza Hosseini, PhD – Managing Director at RadonMarket, R&D Manager & NRPP MFM Certified Radon Professional at Niton srl Like any other measurement activity, Radon gas measurement needs a quality program to evaluate and assess the test results. A Radon quality measurement program consists of Quality Control (QC) and Quality […]
RADON IN PILLOLE: DO RADON LEVELS INCREASE WITH THE AGE OF A BUILDING? 📽️ In this video, we will answer this common question: 🗯️Do radon levels increase with the age of a building?❓ No. Actually, there is no relation between the age of a building and its Radon level. Let’s […]

RADON SHORT ARTICLES: “HOW TO KNOW IF A RADON MITIGATION SYSTEM IS WORKING PROPERLY?” There are several methods to lower Radon levels in a building. The recommendation is always to prevent Radon from entering the house. In some cases, there is no choice rather than reduce Radon after it has […]
Reza Hosseini, PhD – Managing Director at RadonMarket, R&D Manager & NRPP MFM Certified Radon Professional at Niton srl There are three main forces that cause Radon laden soil gas to enter buildings. We learned from the previous articles that these forces are: ✅ Stack effect or chimney effects, ✅ […]
