Scope
Exposure-response function for short-term (acute) exposure to ambient air particulate matter (PM) with an aerodynamic diameter < 2.5 µm and restricted activity days (RADs). RAD is defined as a day when a person needs to change his/her normal activities because of ill-health. It is based on surveys among general population. In terms of severity, RADs include: 1) days needed to stay in bed, 2) days of work/school (WLS) and 3) days of other, less serious restrictions on normal activity (MRADs).

Definition
Data
Ostro (1987) [1]
Restricted activity days (RADs) among adults aged 15-64:
- 0.475% (95% Cl 0.417%, 0.533%) increase in RADs per 1 µg/m3 PM2.5
- change of 902 RADs (95% Cl 792, 1013) per 10 µg/m3 PM2.5 per 1000 adults
- Assumes a background rate of 19 RADs per person per year, equivalent to a prevelance of 5.2%[2]
