This study introduces a sensitive neutron dosimeter using superheated liquid for accurate dose monitoring. The device can detect neutron doses as low as 0.1 microSv, crucial for accelerator and reactor safety.

Area of Science:

  • Nuclear physics and radiation detection.
  • Materials science and phase transitions.

Background:

  • Neutron dosimetry is critical for radiation safety in nuclear facilities.
  • Existing neutron dosimeters have limitations in sensitivity and range.

Purpose of the Study:

  • To develop a highly sensitive neutron dosimeter.
  • To evaluate the performance of superheated liquids for neutron detection.

Main Methods:

  • Utilized superheated liquids as the sensitive medium.
  • Employed a volumetric method for nucleation measurement.
  • Irradiated samples with a 3 Ci Americium-Beryllium (Am-Be) neutron source.

Main Results:

  • Demonstrated the capability to measure neutron doses as low as 0.1 microSv.
