Prot ection
a.
against the primary radiological effects, distance will provide
protection.
b. -Against the secondary radioactivity hazards from radioactive fission
products, induced radioactivity end unfissioned residue, detection and avoidance provide the best protection.: Suitable instruments indicate both the
presence and intensity of redioactivity at a given place. Area reconnaissance, the maintenance of contaminetion situation maps, the posting .
of areas of hazard, and minimizing the spread of contaminated meterial into
uncontaminated areas constitute the active measures for reducing the radiological hazard.
c.- Personnel within an operational radius of ground zero who are to be
facing in the direction of the flash will be required to wear special goggles
to protect their eyes ageinst excessive light. Personnel within the zbove .
operational radius who are not provided geggles will face, .with eyes closed,
in the oppesite direction from the flesh, After ten (10) seconds » such
personnel may turn ebeut and observe the phenemena.

Anticipated Hazard Areas
a.
Immediately under the bomb burst there will be an area ef intense
radioacitivity extending downward and to seme extent crosswind and uowind
with gradually decreasing intensity.
b.- Extending downwind,. (and to some extent crosswind and upwind) an air-
borne radioactive hazard will exist. Its characteristics will depend on the
meterological influences such as wind speed and direction at various
altitudes up te the macmum height reached by the cloud,
c, Contaminated water in the lagoon adjacent to the shot site may be of
conseouence, and will be analyzed by the radiological safety unit of TG 7.1
immediately after shot time end at other intervals, d,
Unless care is exercised, individuals er objects entering contaminated
areas may transfer radioactivity to cleam areas,
DNA
e. By means of instruments, such as Geiger-Mueller counters, ion chambers
or phetoelectriclls it is possible te detect the area of contamination and
to measure the intensity of the radieactivity, Radiation intensity will .
normally be measured end reported in reentgens per hour, Besides those
