Manyofthese lesions are solid cellular or papillary; sections A (15), C (23), and D ( x40) are from subjects (No. 15, 1969; No.8, 1972; No. 40, 1973) whose thyroids contained no frankly malignantlesions. Section B ({ x52) is from subject No. 2229, 1969. Estimated doses to the thyroid (in rads) were (A) 855, (B) 31, (C) 450, and (D) 335.
