|Mortality risk by inhalation and ingestion|
The risk of cancer mortality across a lifetime has been calculated for several radionuclides, including plutonium. They are related to a intake by inhalation or ingestion of 1 Bq1 Bq (Becquerel) of plutonium activity. While risks by ingestion are the most common exposure, the ones by inhalation are greater: 8 out of 10 million people per becquerel against 3.5 out of one billion except in the case of plutonium-241 (beta emitter) for which the risk is lower.
