lledioal Facilities. - Field first aid stations were

established on the basis of one per one thousand etiployees up to tive

thowaand, and one etation for each two thousand er.iployees thereaf'ter.
Serious wounds or traotures were not attended at the aid stations but
were treated at the field hospital.

The field hospital was first located ,

about a mile and a halt from Y-12, but in August 1943, it was mowd to a
new buildinc; in the Y-12 Area.

Five physiclan8 and eight regietered

nuraes 1tafted the hospital durint; the pee..k construction period.

Two

ambulances at Y-12 provided eervice to Knorville when neoeaaary.

In

Bovem.ber 1943, the hospital in Oe.k

W&s opened, and it performed

practically all medical services beyond the limitations of the aid

stations anrl the field hospital.
