摘要

The peripheral blood lymphocyte chromosomes of the Filipino, the carabao, the goat, and the ricefield rat, four mammalian species found abundant in the environs of the Philippine Nuclear Power Plant (PNPP-I) in Morong, Bataan, were studied to establish their radiosensitivities and to explore their possible use as biological indicator of radiation effects. The four mammalian species were found to be radiosensitive to gamma-irradiation of whole venous blood. The aberrant chromosomes may be categorized by cytogenetic technique into chromatid and chromosome types. Dicentrics were judged to be the most reliable indicator of radiation effects. A suitable medium competitive with a commercially prepared medium was formulated. The radiosensitivity of the four species based on the frequency of dicentrics differs from each other. A calibration curve was constructed to relate exposure to the observed incidence of dicentrics. This curve is very important in the calculation of the dose corresponding to the observed dicentric yield in case of accidental release of radioactivity in the PNPP-I site.
