7.1 The manufacturer packed dosimeter, УС-05С and КЗУ-27 can be transported by any
carrier and to any distances:
-
rail road transportation must be done in covered and clean carriages;
-
when transporting by open air motor transportation, boxes must be covered up with
waterproof material;
-
when transporting by air carrier, boxes must be placed in hermetic heated section;
-
when transporting by sea/water carrier, boxes must be placed inside hold.
7.2 Placement and fixing of boxes during transportation must provide stable position and
absence of shocks.
7.3 When loading/unloading, requirements given on transportation casings should be
kept.
7.4 Transportation conditions:
7.4.1 Margins for external climatic factors for the dosimeter, УС-05С and КЗУ-27 in
non-working state (transportation) are as follows:
-
temperature ...................................................... from minus 50 to +50 °С;
-
relative humidity ................................................ up to 98 % at +35 °С.
7.4.2 The dosimeter, УС-05С and КЗУ-27 in transportation package are resistible to
impact of sinusoidal vibration of the frequency range of 10 to 500 Hz with 0,35 mm shift
amplitude below the crossover frequency, 5,0 g above the crossover frequency (group F3 on
ГОСТ 12997-84).
8 DECOMISSIONING
8.1 Upon expiration of the entire lifetime of the dosimeter, УС-05С and КЗУ-27, prior to
its repair or verification, it is necessary to examine the radioactive contamination of surfaces.
The criteria for making a decision about decontamination and further application are provided by
3.11 of ОСПОРБ-99.
8.2 Decontamination should be done applying solutions of surface-active substances, if
the radioactive contamination level of dosimeter, УС-05С and КЗУ-27 surfaces (including
available for repair) can be decreased below allowed values (table 8.9 of НРБ-99, table 3.11.3,
3.11.4 of ОСПОРБ-99).
8.3 In accordance with pos. 3.7 of СПОРО-2002 the absorbed dose rate near surfaces
(0.1 m) is allowed to use as a criterion for further operation of the dosimeter, УС-05С and КЗУ-
27 contaminated by unknown gamma-emitting radionuclides.
8.4 In the event that the dose rate is exceeded the background by 0.001 mGr/h (1 µSv/h)
after decontamination or the allowed levels of surface radioactive contamination is exceeded, the
dosimeter, УС-05С and КЗУ-27 are considered to be the radioactive waste. The radioactive
waste is classified in accordance with 3 of СПОРО-2002 and handled (utilized) in accordance
with 3.12 of СПОРО-2002.
8.5 The dosimeter, УС-05С and КЗУ-27 allowed to operate after decontamination are
subjected to repair, if they are failed. The dosimeter, УС-05С and КЗУ-27 unsuitable for further
operation, which level of radioactive contamination does not exceed the allowed value, should
be passed to special places of industrial waste disposal.
The dosimeter, УС-05С and КЗУ-27 of expired operation period, which were admitted to
operate after decontamination, are subjected to working state examination. If satisfactory
working state, the period of further operation is established.
