Establishment of calibration curve for X-ray induced micronuclei in the dose range of 0–5 Gy. Curve followed linear-quadratic fit with the coefficients α = 0.0459 ± 0.0038 micronuclei cell−1 Gy−1 and β = 0.0185 ± 0.0010 micronuclei cell−1 Gy−2. C represents, background frequency (0.0077 ± 0.0012 MN cell−1) of micronuclei, in the pooled data of all volunteers.
