Aims:
Directed effort to integrate initial research results, compose draft POLs for use in developing PELs. Assess "synergistic" effects of integtrated risks. Initial "in progress review" to gain approval through the required control boards for needed updates (BRES, HSRB, etc.). The conceptual basis within the CBS Integrated Research plan anticipates the need to approach operationally-relevant performance POLs with an openness in considering how a synergistic effect may result in a decrement of performance that is perhpas not most effectively represented in the same way a PEL represents a cancer risk from space radiation. Since the focus of a Performance Outcome Level does not necessarily reflect “pathology”, the representation to identify “integrated pathways” for the three risks, indicates the need to ensure we understand (and parse out) the potential vs combined effects on operational performance. That performance may not rise to the “pathological-level” associated with “health concerns” only; but rather prior to getting to pathological level of concern, there are likely detectable decrements of operational performance that are of operational concern (e.g., a reaction time that slowed on average by 10% may not be pathological but might be of great concern is a maneuver is required that requires a reaction time closer to 100% of the crewmember’s preflight level of performance). In addition, individual differences in one’s lifestyle, family history etc. can all play a role in one’s cancer risk due to radiation exposure but these inter-individual differences are seldom, if ever, considered in developing PELs for radiation exposure.

Description:
-Initial Performance Outcome Levels (POLs) linked to operationally-relevant performance tasks with identified decrements of performance used to establish Permissible Exposure Limits (PELs). In establishing an operationally-relevant POL, both inter- and even intra-individual differences will need to be considered to assess how performance is trending over time (with "expected" vs "observed" for a particular crew member being monitored for potential decrements). Thus, the PEL that is established will, of necessity, need to provide an “operationally-relevant” determinant of what the permissible limit of the exposure is given one’s POL profile. This is likely to demand an openness to representing the PEL and the risk in a manner that best informs scientifically-informed, operationally-relevant decision-making with regard to mission-relevant and health risks due to performance changes.
