Absolute measurement by the 4πβ-γ coincidence counting method was conducted by two photomultipliers facing across a plastic scintillator to be focused on β ray counting efficiency. The detector was held with a through-hole-type NaI(Tl) detector. The results include absolutely determined activity and its uncertainty especially about extrapolation. A comparison between the obtained and known activities showed agreement within their uncertainties.
采用4πβ-γ符合计数法进行绝对测量，由两个相对放置的光电倍增管穿过塑料闪烁体，以聚焦于β射线计数效率。探测器由一个通孔型碘化钠（铊）探测器固定。结果包括绝对确定的活度及其不确定度，特别是关于外推的不确定度。将获得的活度与已知活度进行比较，结果表明在不确定度范围内两者相符。
