A survey at the bore of a 1.5-T magnetic resonance (MR) imager assessed radio-frequency (RF) exposure. With variable pulse sequences and loading conditions, the RF power density at relevant occupational positions was below measurable limits (less than the threshold limit value for occupational workers of 1 mW/cm2). Exposure to RF fields is below safe limits for personnel who routinely work within an MR imaging suite.
在一台1.5-T磁共振成像仪的孔腔内进行的一项调查评估了射频（RF）暴露情况。在不同的脉冲序列和负载条件下，相关职业位置处的射频功率密度低于可测量极限（低于职业工作者的阈限值1 mW/cm²）。对于在磁共振成像室常规工作的人员而言，射频场暴露低于安全限值。
