The spectrum-shape method has been proposed to determine the effective value of the axial-vector coupling constant, gA in forbidden non-unique β decays. 210Bi is an isotope of first-forbidden non-unique beta decay, the shape function of which strongly depends on the gA value. Due to the short half-life of the 210Bi, the 210Pb (β, 22.3 y) → 210Bi (β, 5.0 d) → 210Po (α, 138 d) decay chain has been adopted by using PbMoO4 crystals. We prepared a detection system with two PbMoO4 crystals in the same crystal dimensions. One PbMoO4 contains a modern lead and the 210Pb radioactivity was measured about 30 Bq/kg. The other PbMoO4 crystal consist of an archeological lead with low 210Pb radioactivity of about 0.2 Bq/kg, which has been used to subtract the external backgrounds. This detection method with the two crystals has shown a good agreement with a previous beta spectrum study of 210Bi.
