The article deals with evaluation of irradiation of an operator of a 1 MW biogas station (BGS), processing silage plant biomass contaminated by 137Cs and 134Cs. External irradiation and internal irradiation by the means of aerosol particles inhalation were considered. For calculation of the external irradiation, a BGS model was created in the MCNP. The calculated total committed effective doses received by the operator during annual handling of biomass contaminated by 1 kBq per kg of 137Cs or 134Cs were 34 or 69 μSv, respectively. Three scenarios of contamination were evaluated: freshly contaminated silage after model accident, silage right after the Chernobyl accident and at the current radiation situation in the Czech Republic.

Neurologic disorders associated with exposure to inorganic and organic forms of MERCURY. Acute intoxication may be associated with gastrointestinal disturbances, mental status changes, and PARAPARESIS. Chronic exposure to inorganic mercury usually occurs in industrial workers, and manifests as mental confusion, prominent behavioral changes (including psychosis), DYSKINESIAS, and NEURITIS. Alkyl mercury poisoning may occur through ingestion of contaminated seafood or grain, and its characteristic features include POLYNEUROPATHY; ATAXIA; vision loss; NYSTAGMUS, PATHOLOGIC; and DEAFNESS.

INFLAMMATION of the LIVER in humans caused by HEPATITIS B VIRUS lasting six months or more. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.
