ASSESSMENT OF RADIOLOGICAL CONSEQUENCES OF THE ACCIDENT INDUCED BY SHELTER ROOFING COLLAPSE (PREPRINT IBRAE-2001-06)

Preprint IBRAE-2001-06

Bogatov S.

An assessment has been done to describe adequately ways of the Shelter roofing collapse (accidental Unit 4 of the ChNPP) as well as lifting and penetration of dust cloud out of the Unit. Expectable air dust concentrations were calculated by two methods – accordingly standard OND-86 recommendations and dynamic compartment model. Integral dust concentrations are similar for both models. Inhalation doses to personnel near the Unit may be of several rem by the order of magnitude, other ways of irradiation are insignificant. Radioactive fallouts and open “ruins” of the Shelter may be sources of dust resuspension and of hazardous air contamination.
