FEDERAL REPUBLIC OF GERMANY
Environmental monitoring at the Kernforschungsanlage
Julich GmbH [22]
1. General comments
As a departure from the earlier annual reports on environmental
monitoring at the Julich Nuclear Research Establishment (KFA), in
which all the individual radioactivity values were presented, only
mean values will be presented in future, except in cases of significant
rises in the environmental radioactivity level or of investigations
carried out for special reasons. The individual radioactivity
values will continue to be presented in the quarterly reports
prepared for the information of the supervisory authorities of the
province of North Rhine-Westphalia (Nordrhein-Westfalen) and the
interested organs of the Federal Ministry for Education and Science.
When there is an unusual rise in the radioactivity level (especially
when the reference levels — 'alert', 'pre-alert' and 'scientific
interest' — laid down by OECD are exceeded), this information
is transmitted direct to the Federal Ministry for Education and
Science (which passes it on to NEA) and to the competent provincial
body.
As the Annual Report for 1970 described in detail the objectives
of the environmental monitoring activities, the measurement programme,
the methods employed and the measurement procedures,
the present report is confined to a description of the modified
measurement programme and a discussion of the 1971 results.
2. Measurement programme
The environmental monitoring measurement programme was
revised in collaboration with the Interministerial Committee of the
Supervisory Authority (Tables XVIII-XX). The earlier measurement
programme was for historical reasons based on the establishment
of a zero level and the measurement of bomb fall-out. When
the measurement programme was revised, due account was taken
of new measurement procedures, of experience pointing the way to
greater environmental monitoring efficiency, and of the principle
of combining amount received and emission monitoring. On 1 January
1972, the measurement programme in operation since 1 April 1971
