All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
Radon concentrations can vary daily, and accurate radon exposure estimates require long-term average radon measurements in the spaces where an individual spends a significant amount of time. [ 173 ] Radon levels fluctuate naturally, due to factors like transient weather conditions, so an initial test might not be an accurate assessment of a ...
Previously, FCA had assembled a different model, also named the 500e, from December 2012 to June 2019 at its Toluca Car Assembly plant in Mexico; this earlier 500e was a BEV derived from the second-generation 2007 Fiat 500 and was sold exclusively in a limited number of states within the United States market.

Radon-222 (222 Rn, Rn-222, historically radium emanation or radon) is the most stable isotope of radon, with a half-life of approximately 3.8 days. It is transient in the decay chain of primordial uranium-238 and is the immediate decay product of radium-226 .
