A discussion of the evidence in this
@ase by one of the authors is presented in the Appendix B
ef this report.
These two cases, drawn from the relatively small number
of individuals so contaminated, strongly Suggest that Pu-239
particles offer a unique carcinogenic risk.
They indicate
that a single particle is capable of delivering an intense
radiation dose to a critical volume of tissue and that this
disruptively irradiated tissue, like an atrophied hair follicle,
has a high probability
(maybe as high as 1/1000)
of becoming
cancerous,

Relatec Luna Experiments
* The skin experiments with animals are remarkable in that
& highly disruptive dose of radiation to a small portion of
repairable mammalian tissue produced frequent carcinogenesis.
The chance of producing one cancer per animal is essentially
unity.
It is reasonable to expect that a comparable
Gevelopment could occur in lung tissue.
While a number of
Fadioactive substances have been used to induce lung cancers
48
in mice and rats, it is difficult to derive any characterization of carcinogenesis from these experiments.
