Balicer, R., Catlett, C., Barnett, D., et al. (2011). Characterizing Hospital Workers' Willingness to Respond to a Radiological Event. PLoS One. 6(10): e25327.
Johns Hopkins Hospital staff were sent an anonymous online survey to assess their willingness to respond to work after the release of a radiological dispersal device (i.e., “dirty bomb”). Of the 3,426 respondents: 39% were not willing to respond to a RDD scenario if asked but not required to do so; those who perceived their peers as likely to report to work were 17 times more likely to respond during a RDD event if asked; 27.9% with a perception of low efficacy declared willingness to respond to a severe RDD event; and perception of threat had little impact on willingness to respond.
