ABSTRACT OF THE DISCLOSURE A radioactive aerosol inhalation apparatus includes a lead-shielded container, having a lid or cover, and a disposable aerosol inhalation device for use in producing properly sized radioactive tagged particles. The disposable device includes a mouthpiece attached to a wye connector containing a valving system for inhalation of the radioactive aerosol and exhalation to an entrapping filter. Conduits are respectively provided by flexible tubing from a nebulizer and to the filter. The optimum range of particle sizes is generated by producing an aerosol in the nebulizer which has- an internal baffle. For ease of handling and to minimize radiation exposures, an entry is provided to add radioactive solution directly into the baffled nebulizer. A method involves using the apparatus to supply an aerosol containing radioactive tagged particles to a subject or patient for treatment and/or diagnosis.
