Another study found that rapid respiratory rates in babies, counted using a stethoscope, were 60–80% higher than those counted from beside the cot without the aid of the stethoscope.

8 h = 1 day 40 h = 1 week 50 week = 1 yr. Therefore, for occupation exposures of that time period, 1 mrem/h = 2,000 mrem/yr 0.5 mrem/h = 1,000 mrem/yr. The U.S. National Institute of Standards and Technology (NIST) strongly discourages Americans from expressing doses in rem, in favor of recommending the SI unit. [7]
More exactly, the mean solar day is 86.400 002 ks due to tidal braking, and increasing at the rate of approximately 2 ms/century; to correct for this time standards like UTC use leap seconds with the interval described as "a day" on them being most often 86.4 ks exactly by definition but occasionally one second more or less so that every day ...
