Description	In two pea cultivars (Lantra, Menhir) changes in isoflavonoid levels caused by UV-A and g - irradiation were investigated. The changes were determined in seeds, seedlings and plants. UV-A irradiation was performed for 0 (control), 24, 48 and 72 hours at l=365.5 nm, P= 125 W, g - irradiation with 60Co at doses 0 (control), 10, 20 and 40 Gy. Cultivars responded differentially to various doses of irradiation in both types of irradiation. Daidzein and genistein are the main isoflavones of biological interest belonging to the group of naturally occurring isoflavonoid phytoestrogens. Daidzein (Dai) and genistein (Gen) were determinated by a selective and sensitive radioimmunoassay 7- and 4´- cross-reactive method. In less amounts was determined biochanin A (Bio A) by means of 7-cross-reactivity. The highest levels among isoflavonoids were found for daidzein-7 cross-reactivity in both pea varieties (in average in Lantra seeds 6 562.4 mg kg-1 DM, in Menhir seeds 3 481.3 mg kg-1 DM).
