100 to 500 mr/hr, radiation levels in the area are higher tut
on fringe and taking observations at lower radiation
levels, cloud is visible, working leading cdge of cloud, dumy,
dummy, readings fluctuating, iadsafo mission progressing
satisfactorily, dummy, plus two dummy five-digit groups."
2.
Post BRAVO medification of above:
=
& Reference paragraph 1 above, and in order to riport actual
values of the intensity reading instcad of the blockevalues given by the
second digit, a change was made whereby the successive digits of the first
available dummy five digit group was used to indicate tho specific valuc
of the reading within the blockevalue given.
Thus, [ff the block-value
were 500 = 1000 mr/hr, followed by the group 75022, the true reading would
be 750 ar/hr. This change also made use of tho last
t of the group
to indicate the type of instrument used, 1.6., 1 for aN/PO%T13 and 2 for
Seintameter, 75022 thereforw would completely designate a reading of 750
or/hr by scintametor,
be
oferones paragraph 1 above, the second digit was desimed
to indicate intensity readings abowe estimated background,
‘This was
changed to indicate groes roadings in order that tho true intensity of
exposuro on the aircraft crew could be assessed. in the interest of
floxibility in the reporting procedury provision was made for the aircraft
crew to report estinatod aircraft background vy using the first digit to
indicate "no dotectable radiation abowe background,” the second digit to
indicate the blockevalue of the estinated background reading and the
successive digits of the next five digit group to indicate the actual
intensity reading in or/hr in accordance with paragraph 2a above,
