Łódź Radiocarbon Dates III [PDF]

open access: yesRadiocarbon, 1984
The results presented in this list were obtained from 1986 to 1989. Equipment, measurement and treatment of samples are as reported previously (Kanwiszer & Trzeciak 1984: 111). Age calculations are based on a contemporary value equal to 95% of the activity of NBS oxalic acid standard and on the conventional half-life for 14C of 5568 ± 30 years ...

Groningen Radiocarbon Dates IV [PDF]

open access: yesRadiocarbon, 1963

We have not succeeded in preparing all the measurements done in this time; the present list contains a more or less random selection. It is hoped the rest will be included in next year's list.
