How to fix appropriate radius(r) for the significance test in Kth nearest neighbor clustering?

What value of radius(r) is to be choosen for the significance test in Kth nearest neighbor clustering ? (Clustering variables are measured in same scale and hence, no standardization is required in my data).

This is pretty much a decision based on knowledge about the nature of the data. You have to make a choice as to an appropriate value, combining your need for successful discrimination with the anticipated granularity of the clusters. Arbitrary values make little sense.
