Narrative:

During preflight walk around; paperwork was handed to me with radioactive material in belly and nose. I ask what is the exposure duration for the flight; and no one could tell me so I said the material needs to come off. Captain has not arrived; but he will make the final determination. Captain arrives and looks at paperwork; ZZZ station manager along with [operations] chief discusses issue and I speak with [operations] chief on phone. Captain references the ppm radiation chart showing load is within limits. I explain to both [operations] chief and ZZZ station chief that paperwork needs/should include total exposure to crew and passengers during flight. Both [operations] chief and ZZZ manager agree our paperwork should reflect that. Consequently; we proceed with the flight. My concern was strictly safety related for myself; crew; and passengers. I believe strongly this information; when carrying hazardous cargo (radioactive cargo); needs to be included. I promised the [operations] chief I would submit a report. [We departed] 2 minutes prior to scheduled departure time. Potential information missing on paperwork. Exposure duration for entire flight.
