Abstract

Effect of DECT cordless phone radiation on exposed, laboratory cultivated upland cotton plants Stefi AL, Margaritis LH, Christodoulakis NS. The effect of the non ionizing radiation on exposed, laboratory cultivated upland cotton (Gossypium hirsutum L.) plants. Flora: Morphology, Distribution, Functional Ecology of Plants [Internet]. 2017;226:55 - 64. Abstract A series of experiments was carried out to investigate possible structural or biochemical alterations in Gossypium hirsutum plants after a long term (21 days) exposure to non ionizing radiation (1882 MHz) emitted from the base unit of a cordless DECT system. Exposed plants, compared to the negative (matched) controls, seem to be seriously affected. Notably lower biomass production for the above ground part and the root was recorded. Reduction of the photosynthetic pigments and severe damage of the chloroplast structure were also observed. It seems that non ionizing radiation can be noxious for plant life functions. scopus.com 84997817372&doi=10.1016%2fj.flora.2016.11.009&origin=inward&txGid=2a0c5f11e55ffcd3b656cd415c1041ac Excerpt [same exposure setup as the maize study] The effect of the non-ionizing radiation at the microwave band, on the Gossypium hirsutum young plants, after a long termexposure, can be considered as significant. The disastrous effect on chloroplast structure, the reduction of the photosynthetic pigments and the suppression of the photosynthetic potential, are the main causes for the significant reduction of the primary productivity. Moreover, a serious effect on the underground part of the plant was recorded but this cannot be evaluated yet.
