The protective ability of thiourea in five different concentrations ranging from 5 × 10−2M to 1 × 10−5M has been demonstrated on chromosome aberrations in root tips of Allium cepa exposed to 350r X-irradiation. It was shown that protection against radiation-induced chromosome fragments and anaphase bridges was attained when the germinating seeds had been treated with thiourea for 1 hour prior to irradiation.
