仪器中子活化分析中,待测样品经活化后需经过冷却、拆样、重新封装、传输和测量等过程。其中样品拆样、封装进样是操作人员接触放射性剂量最多的环节。为减少人员接触放射性,同时进一步提高实验室样品分析能力和自动化程度,本工作设计了样品进样装置,如图1所示。此装置主要由样品架(5)、步进电机(6)及其驱动控制柜(10)、直线导轨、回样仓(3)、气缸(2、4、8)、传输管道(进样/回样 Instrument neutron activation analysis, the sample to be tested after the activation of the need to go through cooling, sampling, re-packaging, transmission and measurement processes. One sample demolition, packaging injection is the operator contact with the most part of the radioactive dose. In order to reduce personnel exposure to radioactive substances, while further improving laboratory sample analysis capabilities and automation, this work designed a sample injection device, as shown in Figure 1. The device mainly consists of a sample rack (5), a stepping motor (6), a drive control cabinet (10), a linear guide rail, a sample returning warehouse (3), cylinders (2,4,8) Back to sample
