Contamination with radiopharmaceuticals in nuclear medicine centers in addition to being a health concern requires time-consuming decontamination efforts. According to NRC (Nuclear Regulatory Commission) contamination should be monitored in nuclear medicine centers where radiopharmaceuticals are prepared and administrated at the end of each working session; otherwise, contamination spread...

The effect of intra-arterial histamine on fingertip blood flow (FBF) and vascular resistance (FVR) was studied in normal subjects during reflex sympathetic vascoconstriction induced by body cooling and vasoconstriction caused by intra-arterial noradrenaline. In a room at 20 degrees C, FBF increased from 15.3 +/- 35.5 (SD) to 28.3 +/- 55.9 ml min-1 100 ml-1 of tissue and FVR decreased from 23.7 ...

In order to establish guidelines for exposure of astronauts to iodine, used as a water disinfectant in space, we studied the usefulness of hair, saliva, and urine for biological monitoring in humans and in the human hair/nude mouse model. The monitoring of iodine in patients that received 150 mCi of Na131I (carrier-free) showed similar patterns of elimination for blood, saliva, and urine. The m...

Objective(s): The aim of this study was to determine whether high-dose radioactive iodine (Na131I) outpatient treatment of patients with thyroid carcinoma is a pragmatically safe approach, particularly for the safety of caregivers. Methods: A total of 79 patients completed the radiation-safety questionnaires prior to receiving high-dose radioactive iodine treatment. The questionnaire studied th...
