Ag. Volkovich et al., Measurements of photon ionizing radiation fields in the reactor room of the 4th power-generating unit of the Chernobyl nuclear power plant, ATOM ENERGY, 88(3), 2000, pp. 206-209
A radiation examination of the reactor room of the damaged fourth unit of t
he Chernobyl nuclear power plant was performed. The most strongly radiating
surfaces were determined. Digital maps of the distribution of the effectiv
e surface activity on the inner surfaces of the room were constructed from
the measurement results. 4 figures, 1 table, 10 references.
