Fruiting body radiocesium activity changes with Prussian blue content changes converted to 220 Bq/kg sawdust media. The regression curves of FMC 239 and 245 fruiting body radiocesium activities cultivated with sPB were y ^a = 23.3x ^{b −0.85} (r ^c = 0.96, P ^d < 0.01) and y = 20.8x ^−0.88 (r = 0.97, P < 0.01), respectively. The regression curves of FMC 239 and 245 with iPB were y = 13.3x ^−0.99 (r = 0.82, P = 0.03) and y = 12.1x ^−1.03 (r = 0.85, P = 0.03), respectively. sPB and iPB are described in the text. a–d as in Fig. 2
