摘要:Two economic and practical technics of quantitative boron - coating for radiation detectors which named dip - coated boron deposition ( DCBD) and hand - painted boron deposition ( HPBD ) were presented, and the concrete steps are detailed. After been wrapped by tubes with different thickness and exposed by standard Am - Be neutron source, response of neutron count rate of a boron - lined proportional counter( BLPC) in which the boron film are painted by this way are measured. Minimum of resin - boron ratio(λ) in DCBD is 5. 0, while the best value in HPBD is 0.2. The best method is that mixture be dropped on the coated surface firstly , then print boron powder by hand. DCBD have merits of uniform and firm boron film, and unlimited to coated surface, but it will lower the detection efficiency because of a big value of"λ", Test numbers of DCBD should be determined by experiments and experience, which would waste materials inevitably. HPBD overcomes the demerits of DCBD, but there are some restrictions to coated surface, as a whole, the uniformity and robustness of boron film are not as good as DCBD. Both DCBD and HPBD show simply operation and low cost, which can meet the demands of general gas detectors and can be popularized in domestic research institutions.%报道了2种廉价实用的辐射探测器定量涂硼技术——浸没涂硼和手工刷涂,并给出了详细的涂抹细节.用不同厚度聚乙烯管包裹该方法研制的涂硼正比计数管,经标准Am-Be中子源辐照后测得了其对中子计数率的响应.浸没涂硼脂硼比λ最小值为5.0,手工刷涂λ最佳值为0.2;最佳方法是先在待涂面上滴混合液,再撒上硼粉刷涂.浸没涂硼对待涂面无限制,且硼膜均匀、牢固性都较好,但因λ较大而降低探测效率,且浸涂次数需实验和经验确定,还会造成浪费.手工刷涂克服了浸没涂硼的缺点,但对待涂表面形状有要求,且其硼膜的均匀、牢固性总体不如浸没涂硼.两种涂抹工艺操作简单、成本低廉,且能达到要求,可以在国内相关单位推广使用.
