Area of Science:

  • Nuclear physics and radiation protection.
  • Computational modeling of radiation transport.

Background:

  • Privately owned facilities in the U.S. processed radioactive materials for atomic weapons production.
  • Understanding radiation exposure is critical for worker safety in historical nuclear sites.

Purpose of the Study:

  • To model and determine gamma ray and bremsstrahlung dose rates from natural uranium metal.
  • To assess dose rates from various geometrical configurations encountered by workers.

Main Methods:

  • Seven representative geometrical objects of natural uranium metal were modeled.
  • Dose rates were calculated using two distinct computational codes: MCNP5 and MICROSHIELD.
  • Both gamma ray and bremsstrahlung components were calculated and combined for total dose rates.

Main Results:

  • MCNP5 and MICROSHIELD models yielded comparable total dose rates, ranging from 51-84 microSv/h and 17-95 microSv/h, respectively.
  • The contribution of gamma rays and bremsstrahlung to the total dose rate was of the same order of magnitude for each object.
  • Good agreement between the two modeling methods was observed despite differing assumptions.

Conclusions:

  • Computational modeling provides reliable estimates for radiation dose rates from natural uranium.
  • The findings support the assessment of historical worker radiation exposure at atomic weapons production facilities.
  • Consistent results from MCNP5 and MICROSHIELD validate their use in similar radiation safety assessments.
