Touch of Lady Grey proc question

Hi folks,
just a quick one. I'm looking at slotting Touch of Lady Grey into my Rad defender's Radiation Infection (which is a targetted AoE toggle), and I was wondering if the damage proc would apply to everyone in the area of effect, or just the target themselves.
Thanks in advance

Everyone in the area (proc chance pulsing every 10 seconds).

edit to clarify: it rolls a chance for each target in the area separately, so anywhere from zero to all of them could get procced on.

Fantastic. This was exactly the information I was was hoping for.
Thanks.
