ination is usually distributed in the body's extracellular fluid, and a large proportion appears in the thyroid gland. This selective deposition provides a convenient means of assessing the extent of individual contamination. Buchan and Brindle estimated by scintillation counting the amount of iodine-131 in the thyroid glands of each of 39 persons whose households contained a patient recently treated for hyperthyroidism with this isotope. In most of the families the recommended precautions were observed, but in a few, selected for intelligent understanding of the purpose of the survey, the precautions were ignored. In almost all of the 39 persons iodine-131 was readily detected in the thyroid. The doses of radiation they received from it were small,though they were larger than the dose incurred by the thyroid or other organs from a year's radioactive fall-out at present levels. In some instances they were comparable to a year's natural background radiation. Further experiments are in progress to estimate the additional dose due to external gamma-radiations from the patients. Buchan and Brindle suggest that, except where very young children are concerned, precautions to minimize contamination from iodine-131 in the home should be abandoned and that no restriction is needed on the amount of this isotope that may be given to outpatients-even at the level of 200 millicuries or more used in the treatment of thyroid carcinoma. These proposals may not be readily accepted, but the Plymouth study does show that the contamination hazard is adequately contained by the present regulations.
