ばく露装置
ばく露の発生源/構造
チャンバの詳細 Two R18 hollow rectangular waveguides (131 mm x 65 mm x 425 mm) operating in TE10 mode were used with a removable short cut making them a resonating cavity. They were equipped with ventilation holes, a fan and several sensors. Data from all sensors (field strength, air temperature, fan driving current) were collected every 10 s in a data logger also controlling the GSM frame unit and the RF switch. The whole setup with dimensions of approx. 50 x 25 x 45 cm³ was placed in a CO2 incubator.
ばく露装置の詳細 Six 35 mm Petri dishes fixed in two holders were placed in each waveguide, and in the H-field maxima being separated by 106 mm. The amplified RF signal was connected to one of the waveguide cavities by a computer-controlled switch enabling a double-blind study design.
