Amit89,
I recommend getting copies of J442 (
http://standards.sae.org/j442_201302/) that will show you what equipment you will need. Then you'll need a copy of J443 (
http://standards.sae.org/j443_201006/) that describes how you use the items in J442 to calculate intensity.
That is just the beginning. You will likely need to review other specifications depending on what industry you serve.
I'm guessing you're new to the shot peening world so I'd also like to recommend visiting
