The worse case exposure condition of the thermal imager currently available at ISG is shown in Figure 4. In this
application, the firefighter is surveying a fire scene prior to entering a burning building. His gear is on, but his face
shield is not down. Although this is the worse case configuration from an exposure standpoint, it is not considered
normal use since typically the transmitter will be off. However, there is a possibility that it may be on.
The dimensions of the Talisman are shown in Figure 5. The distance from the antenna to the LCD display is
approximately 25cm. Keep in mind that the camera is internally shielded against electromagnetic interference
(EMI). This will also provide additional safety from RF exposure. The proposed location of the antenna is shown
Figure 3. ISG Thermal Systems USA Talisman line of thermal imagers shown in its typical application.
Figure 4. The dimensions of the Talisman are shown above. The antenna will be placed on the end of the camera with the detector and lens,
opposite the display.
