Ionising radiation measurement circuit - has counting tubes in probe connected by cable to remote control system which produces operating voltage from tubesA coaxial cable is used to transmit the amplified pulses to a distant measuring instrument and to transmit the operating voltage for the counting ...
aIn contrast to this isthe moderate, or even absent, reaction to the normal backround ionising radiation from radon,which is a much greater risk to health for the population at large. 与此对比是适度,甚至缺席,反应到正常backround电离的辐射氡气,是一种更加巨大的风险到健康为人口在大。[translate]...
The tumour induction model consisted of the mean glandular dose for a two-view screen-film mammogram and the probability of tumour induction from radiation (BEIR 7, 2006;Zoetelief et al, 2006). The preclinical tumour growth model consisted of the mean and s.d. of the preclinical period base...
