The Windscale piles have been closed down for over 30 years and questions about the exact cause of the accident may seem academic; however, its health impact is still very much a live issue, and several assessments of it — from zero upwards — have been made (see Appendix X). Variations over the years are due, as we shall see, to three factors: recognition of pathways to human beings previously discounted; revised estimates of the quantity and composition of the radioactive emissions from the damaged reactor; and — most importantly — changing assumptions about the relationship between dose and effect at low levels of radiation.
