Abstract

The aim of this study was to evaluate the impact of low internal exposure to 137Cs on L. sativum meristem cells and Tradescantia stamen hair cells. It also compared the impact of 137Cs internal and external irradiation of similar level on the plant seed germination and root growth. Compared to control, the tested internal (0.0007 mGy to 0.7 mGy) and external (0.04 mGy to 5.5 mGy) 137Cs ionising radiation doses stimulated the elongation of L. sativum roots by 11 % to 12 % and 24 % to 33 %, respectively. Internal 137Cs exposure (0.0003 mGy to 0.5 mGy) for 14 days caused 1.2 % to 1.6 % of somatic mutations and 19 % to 87 % of non-viable stamen hair in Tradescantia.
