meteorite active area is 45m radius (also a 45m radius from any meteorite portal that is open so may be more than that if the meteorite becomes further activated by a player nearby)
the regen bomb will be disabled if the regen bomb radius intersects the active area radius(es), so if the regen bomb has a 30m radius, then roughly speaking 75m from the meteorite.
the meteorites should not spawn roughly within 4 chunks (64m) of a beaconed plot.
