Artikel 69

The following inspection activities may be conducted and techniques used, in accordance with the provisions on managed access, on collection, handling and analysis of samples, and on overflights:
a) Position finding from the air and at the surface to confirm the boundaries of the inspection area and establish co-ordinates of locations therein, in support of the inspection activities;
b) Visual observation, video and still photography and multi-spectral imaging, including infrared measurements, at and below the surface, and from the air, to search for anomalies or artifacts;
c) Measurement of levels of radioactivity above, at and below the surface, using gamma radiation monitoring and energy resolution analysis from the air, and at or under the surface, to search for and identify radiation anomalies;
d) Environmental sampling and analysis of solids, liquids and gases from above, at and below the surface to detect anomalies;
e) Passive seismological monitoring for aftershocks to localize the search area and facilitate determination of the nature of an event;
f) Resonance seismometry and active seismic surveys to search for and locate underground anomalies, including cavities and rubble zones;
g) Magnetic and gravitational field mapping, ground penetrating radar and electrical conductivity measurements at the surface and from the air, as appropriate, to detect anomalies or artifacts; and
h) Drilling to obtain radioactive samples.
