A Dosimetric Study for Experimental Exposures of Vegetal Tissues to Radiofrequency Fields

摘要

The paper aims to calculate the specific absorption rate (SAR) in a sample composed by a group of plant seeds exposed either to a very low-level 900MHz radiation or to a high level 2.45MHz radiation. The exposure systems were a TEM cell and a microwave oven respectively, and the incident electromagnetic wave was a continuous one. Since interesting biological effects were observed in both exposure cases after plantlets were developed from irradiated seeds, a proper dosimetric assessment was needed. In present work four dosimetric approaches were applied and the results, limitations and uncertainties are discussed.
