Portal attack power in ingress

ingress

Does anyone have the formula for how much a portal can hit you for, when you attack it?
Does the range of the portal attack increase according to portal level?
What is the maximum a portal can hit you for, if it's level 8 and have both turret and force amp?

Can you get hit by more than one portal if you fire a single xmp?
If so, will you take twice as much damage if the portals are identical?

The Ingress Portal Attack Simulator gives a very good indication of the portal's attack strength - the author is currently updating for the new shield and link mitigation.

You can get hit by many portals at once - all the ones your xmp hits. The effects add up - you lose XM incredibly rapidly in a built up area, hence the need for tactics such as attacking from an edge and moving inwards if you are a low level player.

As an L8 it is fun just to go in all guns blazing (but expecting to use up a few Power Cubes) - I'll try and dig out a screenshot I took when I hit 20-something portals in one shot in Manchester city centre
