This question already has an answer here:

I have some points (population) and using function Kernel Density i have calculated population density, then i reclassified the information. Now i would like to use the population density data in "union"function but the problem is that the input data has to be polygons! How can I solve this problem? I'm using ArcGIS10.

You need to convert your raster data to vector (polygons) using the Raster to Polygon (Conversion) tool.
