The main principles and peculiarities of the Ukraine’s Radiation Safety Standards (UkrRSS-97) in comparison with
RSS-76/87 and IRPC standards are considered and analyzed. The problems of NSC KIPT Acceleration Complex
transition to UkrRSS-97 and the way of their settling are discussed.
PACS numbers: 6
1 UkrRSS-97 MAIN PRINCIPLES
UkrRSS-97 order four groups of regularities which
are adapted in conformity with conditions of human or-
ganism exposure to radiation [1] such as:
occupational activity;
medical treatment;
nuclear accident;
natural sources.
From the viewpoint of radiation protection the cur-
rent and promising works at accelerators belong to the
occupational activity. Actions on radiation safety in the
occupational activity should be realized by the following
principles [1]:
worth of activity;
optimization of radiation protection;
not exceeding the established dose limits.
Optimization of radiation protection is the most ef-
fective at the project stage. If therewith one selects, as an
individual dose limit in the optimization range, the value
being less than the main limit, then the fulfilment of the
“not exceeding” principle is assured and comes to the
formal testing and control [2]. For the personnel a crite-
rion of fulfilment of the “not exceeding principle” is the
well-known equality [1 - 3]:
∑ ≤+
i
ii ALIILDE 1// ,
where LD - the annual dose limit;
ALIi - the limit of inhalation i- nuclide entering;
E - real annual dose of external radiation;
Ii - real annual inhalation i-nuclide entering.
Taking into account that for NSC KIPT accelerators
the inhalation radionuclide entering into the human or-
ganism (in the form of aerosols as well as gases) can be
neglected, we obtain:
E/DL ≤ 1.
According to UkrRSS-97 by the value E as used
herein it is intended an effective dose. The effective
dose limit DL=20 mSv (2 ber) in the average for five
consecutive years but no less than 50 mSv for each sep-
arate year. These limits coincide with corresponding
recommendations and international standards [2, 4].
2 PECULIARITIES OF UkrRSS-97
Distinction between UkrRSS-97 and RSS-76/87
does not consist in the mechanical decrease of the dose
limit. Firstly, the notion (physical sense) itself of a dose
in comparison with its limit is changed. Secondly, the
five-year period of averaging the annual dose is intro-
duced. Thirdly, the sphere of radiation safety standards
is modified and extended.
All this leads to the necessity of changing, in some
details, the system of radiation dosimetric control, con-
ducting measurements and interpretation of the results,
taking administrative decisions etc.
According to the IRPC recommendation [2] the for-
mer notion “equivalent dose” is given practically to the
new dose value (mean dose in the organ). Some key no-
tions of new radiation safety standards (effective dose,
occupational activity, optimization, hazard, damage
etc.) were not included in the former normative docu-
ments. In turn, UkrRSS-97 does not contain some usual
standards (permissible dose rate PDR, permissible flux
density PFD for gamma- and neutron radiations, per-
missible content PCA etc.).
Distinctions in theoretical and experimental funda-
mentals of UkrRSS-97 and RSS-76/87 are substantiated
also by the results obtained for the last two decades in
different fields of knowledge (radiobiology, medicine,
dosimetry etc.) on which the radiation safety science is
based.
3 PROBLEMS OF TRANSITION TO
UkrRSS-97
From the above it follows that there are the objective
reasons due to which UkrRSS-97 seems to be more dif-
ficult for understanding and practical application.
Though, in fact, the conception of an effective dose and
the use of an equivalent dose in combination with IRPC
recommendations for the practical application of radia-
tion monitoring make it possible to draw up more strict-
ly a system of radiation safety in general, and at acceler-
ators in part.
The primary difficulty of applying UkrRSS-97 at
NSC KIPT accelerators consists in that the common
measuring system of individual dosimetric control for
external exposure (thermo-luminescent dosimeter with
accumulators based on detectors from LiF: Mg, Ti in
cassettes with the aluminum filter) does not satisfy the
present-day requirements. According to IRPC recom-

mendation for evaluation of the effective dose from the
external irradiation by the means of individual control
one should measure the value of Hp(10) i.e. the individ-
ual equivalent of a penetrating radiation dose [5]. To de-
termine the conditions under which the existing system
meets the necessary demands for measuring the external
gamma-radiation it is necessary to perform proper cali-
brations and comparisons [6]. At the same time at NSC
KIPT one has not difficulties of principle caused by
putting a lower threshold dose: for the last ten years the
maximum annual dose of personnel irradiation did not
exceed 10 mSv.
So, the main real problems of transition to
UkrRSS-97 can be settled.
