Risk Perception
Our response to a real or imagined hazard is a function of our perception of that hazard. In many situations, hazards are ignored or disregarded. In other situations, they are magnified. Some of the factors which govern risk perception include: familiarity, degree of dread, memorability

– Infection
– Injury
– Adverse events in the medically vulnerable

Potential Health Risks
• From Chronic Exposures– cancers/leukemia from
• cosmic radiation
• cabin air exposures

Conclusions
• Air travel is one of the safest forms of transportation and accident risk is lower now than in previous years
• there are about 22 hijackings per year; and, on average, 100 deaths from all forms of terrorism worldwide per year.
The information reviewed suggests that:
