After approximately 7 mo exposure on
the new system, dogs were exposed to an
aerosol of 239Pu02 sufficient to produce
initial lung burdens of 0.3 to 1.4 pCi.
In vivo whole-body counts (17 keV X-rays)
were made on each dog, beginning on day 6
after exposure; smoke exposures were resumed
20 days after inhalation of plutonium.
