The data show that a 370 MBq injection of FET leads to an estimated effective dose of 3.3 mSv, which is in the range of routine nuclear medicine investigations. The potential radiation risks associated with this study are well within accepted limits. 按一次静脉注射FET注射液370MBq估算,有效剂量为3.3mSv,其值处在常规核医学研究中可接受的有效剂量范围之内。
From Jan. to Sep. of 1992, air samples were collected in an auditorium, from which the 210 Pb indoor air concentration was measured of average value of 4.66 mBq · m-3 ( 3.74-6.24 mBq · m-3). 1992年1-9月采集了一礼堂内空气样品,测得210Pb浓度为3.74-6.24mBq·m-3,平均值为4.66mBq·m-3。
The remarkable differences ( P < 0.01) between groups are the cumulative urine activity, skeletal uptake rate and cumulative skeletal activity every MBq. 结果表明两组间尿的累积活度、骨摄取率和单位注射剂量的骨累积活度(kBq·h/MBq)差异均显著(P<0.01)。
The radiochemical yield of 111In is 4.4 MBq. ~(111)In的放射化学产额是4.4MBq·μA~(-1)·h~(-1)。
It would result in toxicity if the dosage was too great ( great er than 11.1 MBq). 放射剂量过大(>11.1MBq)可产生毒性。
One week after the three rabbits in group C have been induced as models, 44.4 MBq colloidal chromic phosphate 32P was injected into the right knee joint cavity. C组3只诱导成模型1周后,右膝关节腔内各注射32P-胶体磷酸铬44.4MBq。
The nude mice which had been inoculated subcutaneously with lung cancer tissue were randomized into 6 groups according to different dosage of the durg: the control group, 3.7,7.4,11.1,14.8 and 22.2 MBq group. 将皮下已接种肺癌组织的裸鼠按药物不同放射剂量随机分成对照、3.7、7.4、11.1、14.8和22.2MBq6个组。对荷肺癌裸鼠进行肿瘤局部注射90YLC1。
Being free of the toxic MBQ and p-cresol, the larva and pupa stage of the beetle are safe as a protein fodder. 幼虫和蛹均不含有毒性较强的2-甲基对苯醌和对甲酚,用作动物蛋白饲料较安全。
Croup 7 and 8 ( 14.8 MBq and blank control) were remained alive for about 40 d with an average of 30 d. 14.8MBq组、空白对照组(7组,8组)给药后饲养时间最长达40d,平均30d。
