Halo 04 is the only ring that we have data for pertaining to its blast radius - 25,000 lightyears. Whether or not each ring has this same radius, or each one is different, we can't say for sure. However, we are told that, when all the Halos are fired, "all sentient life with enough biomass to sustain the Flood" within 3 galactic radii will be destroyed. This means that, unless the rings do have different blast radii, and are situated in some strange manner, the rings will all have a synergistic effect when fired together, increasing the range several-fold. This means that, even with Halo 04 gone, there is a possibility that the Earth will still be subject to the Halos' weapons.
