Distribution of Normalized Score Statistic (Based on 100,000 Monte Carlo Samples) for Hypothetical GB Childhood Leukemia Case-Control Study (5 Controls per Case) With Variant Assumptions (Radon Dose Only, Gamma Dose Only, No Contribution from In Utero Dose) (Assuming that a 10-year Follow-up Results in 2593 Registrations Among Boys and 1983 Amongst Girls, and Assuming the BEIR V (18) Risk Coefficient (ERR = 32.15 Sv⁻¹))
