In this study, we examined the short-term effects of real-time individual exposure to PM 2.5 on lung function in a panel of 115 healthy adults. We measured individual real-time PM 2.5 exposure and lung
Splet01. okt. 2024 · This is due in part to the fact that radon levels can fluctuate wildly over the course of 24 hours. As a result, short-term tests can result in unnecessary stress or false relief. However, like dating, there are always exceptions to the rule. Sometimes it doesn’t always take many days to get an accurate assessment.
