'This Report extends the concepts and approaches discussed in NCRP Report No. 171 and Commentary No. 24 to further reduce uncertainty in radiation risk assessments at low doses and low dose rates, thereby enhancing the bases for radiation protection guidance'
'This Report is an update 10 y after the publication of NCRP Report No. 160 (NCRP 2009) and is focused on 2016 doses to patients from medical exposures. Occupational doses and doses to caregivers are not included. Discussion of any potential risks and benefits of the use of medical exposures was beyond NCRP's scope of work.'
'This Report has been prepared at the request of the National Aeronautics and Space Administration (NASA). It is the second phase of a two-phase effort intended to provide guidance to NASA concerning the health effects and mission impacts of space radiation exposure on the central nervous system (CNS) of crew members.'
