Radiation trait and radiation protection

[Galen]

The Radiation trait inflict 2D x 60 rads. But do we subtract the radiation protection of the ship in the usual way?
For the radiation shielding it says "... from both natural sources (...) and artificial (including nuclear missiles and meson weapons). ..." So far so good, unless we read the description of the radiation trait which says "If meson weapons are used, ignore radiation shielding - ..."

Does that also count for the normal radiation protection of the ship (500 Points)? This would also mean a ship with radiation shielding would be immune to radiation from weapons?

This would mean that the crew only gets rads if we roll a 8+ (540+ rads). Adding up the rad protection from Equipment/Armor. (In my imagination military crews always wear some kind of suits during battles)

Well ... I'm a bit confused...

Yes (if trait is from a ship scale weapon). Yes just subtract the radiation countermeasure score from the radiation damage score.

For the radiation shielding it says "... from both natural sources (...) and artificial (including nuclear missiles and meson weapons). ..."

This is Radiation Shielding (TL7), High Guard pg 14.

unless we read the description of the radiation trait which says "If meson weapons are used, ignore radiation shielding - ..."

This is Radiation Damage on Large Ships, also on HG, pg 14. Slightly different rules are used where the crew numbers are supposed to be large.

IDK why Meson weapons are suddenly exempt from radiation shielding, when attacking a larger ship. That is an interesting point.

According to the stated rule, an accumulative DM-1 is applied to all actions a ship performs for every 10% of the Hull lost to radiation weapons. If the ship has radiation shielding, use DM-1 every 40%, instead of every 10%.

So, with Meson weapons you would treat it as DM-1 applied every 10% of Hull lost to Meson weapons.
