“…Although many studies 14,17,26,[28][29][30][31][32][33][34] have been conducted on the dose to caregivers/family members of the patients as summarized in Table 2 but no data was found for exposure rate/dose to the general public from the I-131 therapeutic patients. As Table 2 showed that the doses to caregivers/family members of the patients are within acceptable limits, which pointed out that the dose to the general public, will also be in the allowable limits and the patients treated with radioiodine do not contribute a significant radiation dose to the public.…”

Purpose/ Background: To treat the cancerous tissues the unsealed radioisotopes are being in clinical practice since 7 decades. From these unsealed sources, I-131 is the choice of treatment for the treating thyroid cancers. Orally administered I-131 patients are to be kept isolated in hospital for some period until captured activity in the body reaches to national and international limits for the avoidance of unacceptably high radiation exposures to patients' family members and the general public to keep ALARA (as low as reasonably achievable) principal in mind. The main rationale of this study was to calculate the exposure/dose of the general public. Material and Methods: This work presents the exposure rate and dose to the general public in the corridor and the non-radioactive patients admitted in adjacent room from I-131 administered isolated patients treated at NIMRA (Nuclear Institute of Medicine and Radiotherapy) Jamshoro Pakistan. In this study exposure from 23 thyroid cancer patients treated with different activities of I-131 (50 to 200 mCi) from January 2011 to December 2012 were included. Results: The average exposure rate in the corridor was about 5.17 µSv/hr (2.14 µSv/hr to 8.15 µSv/hr) and the cumulative dose to nonradioactive patients residing in an adjacent room was 0.647 mSv (0.192 mSv to 1.664 mSv). Conclusion: This study concludes that the exposure rate to the general public especially the admitted non-radioactive patient in the adjacent room is almost within the limits of 1 mSv as specified in national and international standards.

Objectives: Since 1940s, the clinical use of unsealed radioisotopes has been in practice and after that the radioiodine's oral administration became a gold standard for treating thyroid cancers. To protect the patients' family members/ caregivers and general public from unacceptably high radiation exposures, the therapeutic dosage of 131 I administered patients are mandatory hospitalized in special isolation room until the exposure rate at one meter meets international and national limits. The current study was focused to measure the isolation duration of inpatients treated with radioiodine. Material and methods:The current study presents the duration of hospitalization of patients treated with 131 I therapeutic dosages at Nuclear Institute of Medicine & Radiotherapy (NIMRA) Jamshoro, Pakistan from 2011 to 2013. Thirty Five patients (age range from 18 to 70 years) with cancer of thyroid administered with different activities (50 to 200 mCi (milliCurie)) of 131 I admitted in special isolated room at different times were included in this study. Results:The results indicated that only one (2.86%) of total patients discharged from hospital within first 24 hours of 131 I administration whereas 17(48.57%), 11(31.43%) and 3(8.57%) patients were hospitalized in isolation room for 48, 72 and 96 hours after the administration of activity. Eleven percent of total isolated patients (n=4) stayed for 120 to 144 hours at the hospital. Conclusion:The stay duration of 131 I administered patients at NIMRA shows wide-ranging pattern. Due to rapid clearance of radioiodine form their bodies, more than half of patients stayed only 48 hours.
