what is the differnece between kernel radius and kernel size of a Gaussian filter

When it is said that kernel radius =10 and kernel sigma=5 then what si the mask size of Gaussian filter. Is the mask size is equivalent to kernel radius.

No. For a given window size you can have a Guassian of any width inside that window, from a very narrow one that fits completely inside a huge window (like if the kernel width was 500 pixels but the standard deviation of the Gaussian function was 30), to a Gaussian that is so wide the tails get clipped off (like if the kernel width was 5 pixels but the standard deviation of the Gaussian function was 20). They're independent things.
