Area of Science:

Radiation physics
Dosimetry
Particle detection

Background:

Accurate characterization of radiation fields is crucial for safety and research.
Distinguishing between neutron and charged particle contributions to radiation dose is challenging.
Existing methods may lack the specificity needed for complex radiation environments.

Purpose of the Study:

To develop and describe a novel technique for separating dose and lineal energy spectra of neutrons and charged particles.
To demonstrate the utility of the technique through calibration in a known neutron field.

Main Methods:

Utilized two gas-filled proportional counters with differing wall compositions.
One counter featured a hydrogen-containing wall, while the second had a non-hydrogenous wall.
The differential response of the counters allowed for spectral separation.

Main Results:

Successfully demonstrated the capability to separate dose and lineal energy spectra.
Calibration results in a neutron field validated the technique's effectiveness.
The method provides distinct spectral information for neutrons and charged particles.

Conclusions:

The described technique offers a reliable approach for differentiating neutron and charged particle radiation.
This method enhances the accuracy of radiation dosimetry and spectral analysis.
Applicable for characterization in mixed radiation fields.
