Five species of beans were chosen to observe the effects of intermittent periods and doses of cell phone electromagnetic field radiation (EMR) on germination seeds. Beans were grown under the same environment and the EMR was different. The treatment included two intermittent periods (4 and 24 h) and three radiation intensities (high, low, and check). The frequency of EMR was 1805-1850 MHz. The mean power density was 0.4809 mW/cm2 for high treatment and 1.455 mW/cm2 for low treatment. The specific absorption rating (SAR) values were measured and expressed as units of W/kg for the five beans. The effects of EMR on the germination rates of seeds were inconsistent. Germination differed under EMR treatment for red bean, soybean, and Mologa bean but not mung and Hyacinth bean. The 24 h intermittent exposure had a significant effect on the height and fresh weight of mung beans. Results differed under high, low, and with check. The 4 h intermittent exposure did not significantly affect the height or fresh weight. Hyacinth and mologa beans showed similar results. Only 24 h intermittent exposure with high treatment had a significant effect on height and fresh weight. Under the same EMR and exposure times the received dose was the same. However, bean species had different germination.
