Harwell radiocarbon measurements VIII

Abstract

This is the second of a series of lists of English archaeological dates and contains 176 dates, refering to the period, April 1986 to March 1987. One of three measurement procedures was used as appropriate to the sample size and requirements for measurement precision - standard liquid scintillation counting to a precision of ± 1%, miniature gas proportional counting for the smaller samples and the higher precision (±0.5%) liquid scintillation counting system brought into operation in 1985. -from Authors
