A compilation of data documenting air and ground concentrations, particle size, and isotopic composition of the radioactive effluent from the Kiwi-A series of test reactors, together with descriptions of the sampling and analytical instrumentation are presented in this report. Data are also presented on the indirect radiation from the reactor and radiation due to passage of the effluent cloud for two of the three reactors.

Presented are the results of documentation studies on the effluent from the Kiwi B4D-202 and Kiwi B4E-301 reactors during full power tests. A description of procedures and equipment is also given. An analysis of the environmental effects due to the passage and deposition of released material is given as well as deposition velocities measured at various locations.
