The second and third schools at Bikini and Enewetak were at fended by

These secondary courses were considered emergency supplementary
instruction.
Instructors were TU 7 personnel.
The lack of continuity in operations and the loss of experienced personnel between operations necessitated the establishment of a trhining
program for unit laboratory technicians, photodosimetry technicifins, and
radiological-instrument repairmen.
Schooling for instrument repgirmen was
arranged through JTF 7 and AFSWP at the Naval Schools Command, Tgeasure
Island, San Francisco, and consisted of 1 month of instruction i}
Maintenance and repair of military radiac instruments.

All TG 741 repair-
men were graduates of this school.
Arrangements were made with the Nucleonics Branch of the Sigrfl Corps
‘Engineering Laboratories to conduct familiarization courses with
fnobile
field laboratories for the laboratory and photodosimetry techniciBns.
