中子水份计问世已经三十多年了,最初用于测定土壤的水份,以发展农业、土木工程和水文事业。以后应用于工业部门,测量诸如焦炭、烧结料以及石英砂等物料的水份。根据氢元素对快中子的慢化作用,我们研制了一套插入型中子水份计。该装置由探头和主机两部分组成。探头包含Am—Be中子源、三氟化硼中子计数管和前置放大器。 The neutron moisture meter has been in existence for more than three decades and was initially used to determine the moisture in the soil for the development of agriculture, civil engineering and hydrology. Later used in the industrial sector to measure moisture levels in materials such as coke, sinter and quartz sand. Based on the moderating effects of hydrogen on fast neutrons, we developed a set of inserted neutron moisture meters. The device consists of two parts of the probe and the host. The probe contains Am-Be neutron source, boron trifluoride neutron counter tube and preamplifier.
