チャンバの詳細 TEM cell with outside dimensions of 47.7 x 22.8 x 22.8 cm
ばく露装置の詳細 Two flasks (40 x 105 x 25 mm) were placed inside a vertically positioned TEM cell which was placed inside a cell culture incubator. The flasks were irradiated by a plane wave with the E-field (1 V/m) tangential to the bottom of the flask.
Additional information For each exposed sample, a control was also established and was kept in the same incubator containing the TEM cell.
