  • This is in addition to the role air pollution plays in the development of heart and respiratory diseases, including acute respiratory infections and chronic obstructive pulmonary diseases. (
  • Calibrations are performed by comparing the well-type ionization chamber response to air kerma realized by a NIST primary x-ray standard. (
