please apologies me sir for asking this as you say its the only registered company and that in DRDO as my my know relative are officials of ministry of defense and even i had the opportunity with the regional managers to interact and share the knowledge about radiation and isotopes and the knowledge shared by them and good connectivity and reputation......,

what is the proof that it is the only registered company that you try to degrade and suppress other valid companies .........i even know this company since 5 years and they themselves say they are sister company associated with IAEA which is no where registered with MOD or GOVT of india
