18 10 days after exposure contai ned 0.23 micro grams per gram
burnt material.
The urine samples remained more or less constant for the entire pe riod
and contained radium element equivalent of 2.5 x 10.2 micro grams por gram
evaporated matorial. The original material contained by analysis 058 mgs radio-
active material in the two grams fed the pig.
Our results indicate that 97.85 percent of the material ingested in
twenty days was eliminated by the end of ten dayo after the exposure had ceased.
Or 2.15 percent had been absorbed through the alimentary track and still remained
in the body.
Five pigs whose jaws had been painted regularly each day for a period of
six months during which time each pig had received an estimated dosage of three
grams of the luminous paint containing 2.66 mgs of radio-activo element per 100
grams, were killed too months after the last application of the paint. Their
bodies were burnt to an ash and these ashes examined with radium element equiv-
alent with the following results.

The blanks are normal pigs killed and treated the same way as the radium pigs.
The tests were made by alpha ray comparison which is considered very
sensitive for the detection of radio-active material. Pigs B and E show no
radio-active material. Pigs 0 and D give a slight indication of its presence,
though the time required for a defini te drop in potential is so small as to raise
