Use of CAMRA Wiki
CAMRA researchers welcome submissions to the Wiki. Key quantitative information is needed to undertake a QMRA. This begins with problem formulation and includes articulation of the venue, hazards, exposure pathways and necessary data. We have developed forms or will be developing forms which can be used to fill in key information regarding.
