These cases will be discussed in detail below. Deaths Table 6 lists the times and causes of death in both exposed and comparison populations. The deaths subsequent to the 1964 survey were as follows. 6.3 A 77-year-old womanin the Ailingnae group (No. 43) died of pneumonia. She hadhad arterio- sclerotic heart disease, asthma, and marked pe- ripheralsclerosis with occlusion of the right radial artery, and was quite senile.
