Exposure details   Electromagnetic fields (900 MHz) evoke consistent molecular responses in tomato plants. by Roux D, Vian A, Girard S, Bonnet P, Paldian F, Davies E, Ledoigt G published in: Physiol Plant 2006; 128 (2): 283 - 288 Exposure 1: Main characteristics frequency: 900 MHz type of field: electromagnetic field Modulation type of modulation: continuous wave (CW) Exposure setup exposure source/structure: MSRC exposure time pattern: continuous for 10 min chamber details: The MSRC (mode stirred reverberation chamber) consisted of a large room (200 m³) with a double-layered steel wall, acting as a Faraday cage, an antenna, and movable blades to stir the EMF. Tomato plants were grown inside plywood culture chambers. Shielded chambers were enclosed in a polymer mesh covered with aluminium foil to protect the plants from exposure [Vian et al., 2006]. setup details: When the plants were 3 weeks old, the whole culture chamber was placed in the MSRC (24 h prior to irradiation) in a determined working volume where the field was homogeneous and isotropic. add. information: The fourth terminal leaf (exposed and shielded) was harvested at different times after exposure (0, 5, 15, 30, and 60 min). Exposure parameters parameter: value: remark: electric field strength  5 V/m  average signal amplitude of a GSM phone  electric field strength  40 V/m  close to the French legal emission limit  Exposure 2: Main characteristics frequency: 900 MHz type of field: electromagnetic field Modulation type of modulation: continuous wave (CW) Exposure setup exposure source/structure: same setup as in Exposure 1 exposure time pattern: continuous for 2 min Exposure parameters parameter: value: remark: electric field strength  5 V/m  average signal amplitude of a GSM phone  Reference article Vian A et al.
