  • Title: Is there a difference in radionuclide-induced bone tumor sensitivity between male and female beagles?
    Author: Lloyd RD, Miller SC, Taylor GN, Bowman BM.
    Journal: Health Phys; 1999 Aug; 77(2):178-82. PubMed ID: 12877339.
    Abstract:
    An analysis of bone tumor occurrences among male and female beagles given monomeric 239Pu or 226Ra was not able to establish a difference in sensitivity to induction of bone malignancy by radium or plutonium exposure. This is in contrast to the situation reported for mice. Female mice are substantially more sensitive to 239Pu irradiation than males, but this difference is obliterated by gonadectomy, females becoming less sensitive and males becoming more sensitive. Although there may be some nonuniformity between human males and females for radiation-induced bone sarcoma occurrence, analysis of data sets containing both men and women exposed to 224Ra, 226Ra, 228Ra, or 226+228Ra appears not to reveal substantial differences in sensitivity by gender, a situation similar to that reported herein for beagles.
