If I understand correctly, C14 is produced by cosmic rays and nitrogen and is considered a very steady process thus carbon dating is trusted. The half life of C14 is about years and this method can be reliable up to 50 thousand years. Investigations has been going on to determine what the proportion of 14C in the atmosphere has been over the past fifty thousand years. A calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample’s calendar age. Other corrections which are made to account for the proportion of 14 C in different types of organisms, and the varying levels of 14C throughout the bio system on earth reservoir effects. Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the s and s. Fossil fuels contain almost no 14C, and as a result there was a noticeable drop in the proportion of 14C in the atmosphere beginning in the late 19th century. On the other hand nuclear testing increased the amount of 14C in the atmosphere, which attained a maximum in about of almost twice what it had been before the testing began. To verify the accuracy of the method, several artefacts that were datable by other techniques were tested; the results of the testing were in reasonable agreement with the true ages of the objects. Over time, however, discrepancies began to appear between the known chronology for the oldest Egyptian dynasties and the radiocarbon dates of Egyptian artefacts.

Sara McCorquodale suggests that women meeting strangers on dates meet initially in busy public places, share details of upcoming dates with friends or family so they know where they’ll be and who they’ll be with, avoid revealing one’s surname or address, and conducting searches on them on the Internet prior to the date. Don’t leave drinks unattended; have an exit plan if things go badly; and ask a friend to call you on your cell phone an hour into the date to ask how it’s going.
