Please do cite clam (Blaauw, 2010) in your work, as well as its version (most recent 2.2), calibration curve(s) used (e.g., Reimer et al., 2013) and the settings applied to obtain the age-models. See later for special cases such as mixed marine/terrestrial dates.
Negative radiocarbon ages are calibrated with one of the postbomb curves from Hua et al.
(2013), but the user needs to inform clam which one should be used.
High blood pressure is considered a risk factor for heart disease and stroke, and high BP in childhood has been linked to high BP in adulthood.
Another standard, Oxalic Acid II was prepared when stocks of HOx 1 began to dwindle. The ratio of the activity of Oxalic acid II to 1 is 1.29330.001 (the weighted mean) (Mann, 1983). There are other secondary radiocarbon standards, the most common is ANU (Australian National University) sucrose.You can get an idea of the relationship between C14 and age at the Carbon Dating calculator page. 1950 was chosen for no particular reason other than to honour the publication of the first radiocarbon dates calculated in December 1949 (Taylor, 19). Ninety-five percent of the activity of Oxalic Acid from the year 1950 is equal to the measured activity of the absolute radiocarbon standard which is 1890 wood.The pop-up will identify the percentile line, followed by the age (yrs), then the value being graphed (blood pressure).Mouse-over the subject's data point to see the subject's data values.
