A Simple and Inexpensive Clinical Whole Body Counter

SummaryThe conventional radioisotope scanner has been used as a whole body counter. The background index of the system is 10.9 counts per minute per ml of sodium iodide crystal. The sensitivity and derived sensitivity parameters have been evaluated and found to be suitable for clinical studies. The optimum parameters for a single detector at two positions above the lying subject have been obtained. It has been found that for the case of 131I measurement it is possible to assay a source located at any point in the body with coefficient of variation less than 5%. To add to the versatility, a fixed geometry for in-vitro counting of large samples has been obtained. The retention values obtained by the whole body counter have been found to correlate with those obtained by in-vitro assay of urine and stool after intravenous administration of 51Cr-albumin.

SummaryUsing a whole-body counter, normal whole-body and renal clearances of 203Hg-chlormerodrin and the action of L-cysteine and D-penicillamine as chelating agents have been studied in 19 subjects.L-cysteine and D-penicillamine given in varying doses at different time intervals did not change the whole-body or renal retention of mercury. This indicates that these chelating agents are not effective when mercury is present in the body in minute quantities. The search for better and more convenient renal scanning agents should continue, as should also the search for a better chelating agent to enhance clearance of 203Hg from the body.

Occupational Radiation

Internal radiation dosimetry of occupational radiation workers due to inhalation of 131I during maintenance at iodine 131I hot cell of Radioisotope Production Division (RIPD) of Bangladesh Atomic Energy Commission have been performed with Whole Body Counter (WBC) containing two large size NaI detector. The contaminated radioactivity of the radiation workers by 131I was immediately conducted using a WBC (CANBERRA, FASTSCAN model 2250) and counting was repeated again a few days later. The performance of whole body counter was checked by CANBERRA transfer phantom (model 2257) with a mixed source (20 ml vial). The intake was calculated by Apex-Invivo counting software and then corresponding dose in thyroid were estimated by using Integrated Modules for Bioassay Analysis (IMBA) Professional Plus code modules. The body activity due to intake of 131I and the total effective and equivalent dose in thyroid were also estimated and discussed.
