Yes, you should. The NJ DEP classifies every part of the state as a, “High radon potential” area, “Moderate radon potential” area and a “Low radon potential” area. I live in Monmouth County and conduct the majority of my inspections in Monmouth, Ocean and Middlesex Counties. Radon is measured in pico Curries per liter of air represented as “pCi/L”. A pico Currie is one trillionth of a Currie which is the measurement of radioactivity. The “Currie” is named after Madam Currie who discovered the element radium and due to her exposure to the radio active elements died from her discovery due to exposure.
