LEGENDS Figure 1. Diagramatic sketch showing distribution of fallout. Gamma radiation represented by wavy shaded areas, beta radiation by stippiing. Figure 2. 50% attenuation in akin of various isotopes. Pigure 3. Barly hyperpigmented moculopopular neck lesions at 15 days. Case 39, age 15, F. Figure 4. Extensive lesiong in 13-year old boy at 46 days post exposure. Case 26. Figure 5. Same case as in figure 4 six months after exposure showing healed lesions anid regrowth of hair. Figure 6. Hyperpigmented saised plagues and bullae on dorsum of feet at 28 days after exposure: One lesion on left foot shows deeper involvement. Feet were painful at this time. Figure 7. Same case as in figure 6 six months ister. Foot lesions have healed with repigwentation, except depigmented spots persist in small areas where deeper lesions were. Figure 8. Bpilation in 7-year o14 girl at 28 days after exposure. Case 72. Figure 9. Same girl as in figure 8 six months after exposure showing complete regrowth of normal hair. Figure 10. Section from beta lesion of neck at 3 weeks after exposure to fallout. (X 100) Bpidermis: extensive transepidermal dauwage (with slightly less involved gones on either side). gtanulosum. Loose lamination of atratum corneum, absence of stratun Parakeratinization with exfoliation of pigment containing cells. Disorganization of thea malpigean layer. with indistinct capillary loops. Dermis: mild edema of pars papiliaris Pesivascular cellular infiltrate (lymphocytes and sonomnclear phogocytes), in superficial corius with telangiectasis. Figure 11. Case 26. Section (512 x) from lesion on back of neck at two years after expos- ure to fallout. Lesion showed mottled pigmentation and depigmentation grossly. Section shows some loss of pigment in the basal layers of the epidermis and telangietasis in the dermis. Case 39.
