The invention relates to an alpha, beta and gamma radioactive
aerosol continuous sampling and measuring device which comprises a frame, a sampling chamber, a measuring chamber, a boosting motor, a tape conveying motor, a tape collection plate, a tape feeding plate, a
filter paper tape, a passivated
ion implantation plane
silicon detector and a
sodium iodide detector. The sampling chamber comprises an upper
air chamber and a lower
air chamber, and the upper
air chamber and the lower air chamber are communicated with each other; the top of the upper air chamber is provided with an air inlet, and the bottom of the lower air chamber is provided with an air outlet; the measuring chamber comprises an upper measuring chamber and a lower measuring chamber, and the upper measuring chamber and the lower measuring chamber are communicated with each other; an output end of the boosting motor is connected with an eccentric shaft through a speed
reducer, and the eccentric shaft is connected with both the upper air chamber and the upper measuring chamber through a connecting rod; the tape conveying motor is arranged on one side, close to the measuring chamber, of the frame; the tape collection plate is connected with the tape conveying motor through a speed
reducer; the tape feeding plate is arranged on the other side of the frame; one end of the
filter paper tape is wound on the tape feeding plate, and the other end of the
filter paper tape sequentially penetrates between the upper air chamber and the lower air chamber and between the upper measuring chamber and the lower measuring chamber and then are wound on the tape collection plate; the passivated
ion implantation plane
silicon detector is arranged at the bottom of the upper measuring chamber; the
sodium iodide detector is arranged in the lower measuring chamber.
