Acute high-dose effects are well-documented and understood (mainly through laboratory testing). Lower doses, on the other hand, are less understood, as low dosage research is controversial, and there are only a few studies that use low and ecologically relevant IR levels, particularly those conducted under controlled conditions. The effect of low gamma radiation was investigated in this study using Vicia faba L., Vigna radiata L., and Pisum sativum L. Healthy and viable seeds of these plants were irradiated with varying doses of gamma radiation (Cs^−¹³⁷ source) and sown under controlled environmental conditions. The doses/dose rates used were within the scope of the International Commission on Radiological Protection’s Derived Consideration Reference Level (DCRL) for these groups of plants (1 - 10 mGy∙d^−1), so this study tested this DCRL. Observations were made on certain germination parameters and growth traits like germination percentage and rate, shoot and root length, seed weight, number of leaves, wet and dry biomass, plant height, leaf chlorophyll content, and leaf area. In the germination phase, the doses employed in this experiment did not affect the seeds’ weight, germination percentage, and rate, but there were some interesting effects on the root and shoot length; as all irradiated groups performed better than the control group (particularly the 16.2 mGy and 48.5 %K Ionising Radiation %K Morphometric Parameters %K Germination Parameters %K ICRP DCRLs %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=118349
