从空中勘探放射性矿床,迄今还是在飞行500呎高的飞机座艙里放一个閃光仪来进行的。目前設計出了一种輔助勘探仪,用时把它吊在飞机下面一根长200呎的繩索上。这个勘探仪的形状象个炸彈,放在長約5呎的玻璃纖維外壳里。檢驗器的信号沿繩索傳送到飞机側緣上的記录器。
From aerial exploration of radioactive deposits, so far still flying a 500-foot aircraft cockpit put a flashlight to carry out. An assistive probe was currently designed to hang it on a 200-foot rope beneath the aircraft. The explorer was shaped like a bomb in a fiberglass shell about 5 feet long. The signal of the verifier is sent along the rope to the recorder on the side edge of the aircraft.
