“…Depending upon the renal clearance rates and other patient specific factors, the contamination level varies from patient to patient. The excretory channels for administered radionuclide in therapy are micturition, bowel, salivation, sweating, lachrymal fluid and lactation [28]. Other factors affecting the clearance levels in thyroid carcinoma patients are the variable amount of thyroid remnants, renal insufficiency and patients behaviour like following proper hygiene such as cleaning urine contamination in toilet, faulty urination style causing spillage of urine on flour, clothes changing frequency, bathing frequency, and water intake routine [14].…”

The use of RAI-131 in thyroid carcinoma patients presents a special concern on the environmental radiation safety for those who come in contact with the patients especially after discharge from the facility because of excretion of I131 through perspiration, salivation, breathing and urination. Methods & Materials: The present study was conducted at Nuclear Medicine Oncology and Radiotherapy Institute Nawabshah (NORIN) Sindh from 2017 to 2021 with the objective to evaluate contamination hazards by Excretion made by thyroid cancer patients received iodine therapy stayed in isolation room with doses ranging from 80–200 mCi. The areas included corridor, sink, patient bed, and toilet bowl of isolation rooms before admission and after discharge using LAMSE RM-1001 survey meter. The minimum background radiation level measured before patient stay in isolation room was 0.07 μSv/h while the maximum was 0.40 μSv/h and the mean background reading was 0.18 ± 0.072 μSv/h. The maximum dose rate after discharge was observed at toilet bowl with mean of 9.69 ± 1.98 µSv/hr and minimum of 5.0 µSv/hr and maximum value 13.77 µSv/hr. The readings recorded for the sink were: 2.0 μSv/h minimum, 20.0 μSv/h maximum with a mean of 5.55 ± 1.57 μSv/h while those for the patient bed 0.41 μSv/h minimum, 6.92 μSv/h maximum and a mean of 2.83 μSv/h. the least dose rate was found in isolation room corridor (1.53 ± 0.78 μSv/h) with maximum and minimum values 0.28 & 3.20 μSv/h respectively. Radiation is harmful; safety measures must be ensured to minimize radiation exposure to the family members as well as community either during hospitalization or after discharge of RAI-131 patients. The radiation levels from toilet bowls, beds, sinks, and corridor of isolation rooms were well within the acceptable limits and hence, do not pose significant hazard to the public

“…Even though some guidelines recommend drinking ample water to assist in the elimination of radioactivity on the basis of enhanced diuresis, there is however no large body of evidencebased literature to support this [16][17][18]. In fact, Haghighatafshar et al [18] showed that although inadequate fluid intake and dehydration may reduce the excretion of iodine, increas- ing fluid intake and urinary flow above the physiological range does not significantly increase excretion of RAI.…”

A Case Report of Water Intoxication During Radioactive Iodine Treatment: Why Physicians Should Communicate Clearly With Patients

2020

Radioactive iodine (RAI) treatment is an effective method for the treatment of thyroid remnant ablation and metastasis in patients with differentiated thyroid cancer. The current guidelines recommend patients to drink lots of water to reduce the amount of iodine in the body during RAI treatment; however, water intoxication is a life-threatening condition resulting from hyponatremia. This case report describes water intoxication during RAI treatment in a 55-year-old patient who was evaluated for the management of angio-invasive follicular thyroid cancer following a total thyroidectomy. Hyponatremia is an electrolyte imbalance commonly encountered in oncology practice and is usually defined as a serum sodium level of less than 135 mEq/L. Water intoxication is a rare phenomenon that occurs due to an excessive intake of water, especially when the volume of water intake exceeds the excretory capacity of the kidney. This case report has revealed that all relevant information and instructions including the consumption of water should be clearly and accurately communicated to patients.

“…Radioiodine (I-131) is primarily β-emitting radionuclide with 610 keV energy followed by a 364 keV photon. [1][2][3][4][5] β ray emitted from radioiodine contributes the major radiation dose to the thyroid tissue and the gamma ray photon may give rise the potential radiation hazard to others. 1,2 After first usage of I-131 by Saul Hertz and Arthur Roberts in January 1941 6 , it becomes an admired treatment option for patients with thyroid cancer.…”

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.
