Abstract

In order to estimate the effective dose (E) of a person who may come into close contact to the ^99mTc-GSA patients. Radiation dose rates around 21 adult patients (male: 14, female: 7) were measured with three ionization surveymeters (Aloka, ICS-301) at distances of 0.05, 0.5, 1.0 and 1.5 m from the patients. Measurements were carried out at 0.75, 3.0, 6.0 and 24.0h after the administrations of ^99mTc-GSA.Surveymeters were set up to the first cervical vertebrae (Level I), xiphoid process (Level II) and anterior superior iliac spine (Level III) of the patients with their standing erect, The maximum dose equivalent (H_lcm) rate of 64.98μSvh^-1 per 185 MBq was recorded in the LevelII. Effective half life of ^99mTc-GSA was 5.8h. Total E around the patients were calculated by the initial H_lcm rates and the effective half life. Total E were 285, 62, 23 and 13μSv per 185 MBq at distances of 0.05, 0.5, 1.0 and 1.5m, respectively. E for the first 24h was corresponding to 94.3% of the total E.
