The problem of handling nuclear power plant irradiated structural materials holds one of the central places in the nuclear power industry. High toxic ¹⁰Be with a half-life of T_1/2 = 1.6 × 10⁶ years is discovered in NPP structural materials after reactor operating. ¹⁰Be decays through only electrons' emission. Pure beta emitters are extremely difficult to determine in irradiated structural materials and radioactive waste. We proposed a photoactivation approach for determining the ¹⁰Be activity in NPP samples. The proposed method involves determining ⁹Be and ¹⁰B concentrations and subsequent recalculation of ¹⁰Be activity formed in ⁹Be(n, γ)¹⁰Be and ¹⁰B(n, p)¹⁰Be reactions. The amount of ⁹Be and ¹⁰B is determined by samples' photoactivation using an electron accelerator and ⁹Be(γ, 2n)⁷Be-, ¹⁰B(γ, p2n)⁷Be-reactions. These reactions' experimental yields were measured for 20, 40, and 55 MeV boundary energies of the bremsstrahlung beam. The proposed technique was tested on samples of ChNPP 2^nd unit irradiated structural materials. The technique's calculated error is about 15–20%; the sensitivity is 1 Bq × g⁻¹.

处理核电站辐射的结构材料的问题是核电工业的中心位置之一。反应堆运行后，在NPP结构材料中发现了半衰期为T _1/2  = 1.6×10 ⁶年的高毒¹⁰ Be 。¹⁰ Be仅通过电子的发射而衰减。在辐射的结构材料和放射性废物中，很难确定纯β发射体。我们提出了一种光活化方法来确定NPP样品中的¹⁰ Be活性。拟议的方法涉及确定⁹ Be和¹⁰ B的浓度，然后重新计算¹⁰ Be中形成的¹⁰ Be活性。⁹ Be（n，γ）¹⁰ Be和¹⁰ B（n，p）¹⁰ Be反应。量⁹ Be和¹⁰ B由样本的光活化使用电子加速器和确定⁹为（γ，2 Ñ）⁷ BE-，¹⁰ B（γ，p 2 Ñ）⁷ BE-反应。测量了ms致辐射束的20、40和55 MeV边界能的这些反应的实验产率。所提出的技术是关于ChNPP跟2的样品测试^第二单元辐照的结构材料。该技术的计算误差约为15–20％。灵敏度为1 Bq×g ^-1。
