The "low radiation" sound effect does not sound sustained, but rather comes with a grating rhythm. The sound effect stored in the mod should record a much longer sample in order to bypass this issue.

The sound effect looping issue is made worse by the fact that the script resets it every second, so the sound clips are cut from 3-4 seconds down to 1.

Oh! If it is a longer clip, perhaps the script should select a random 1-second portion of the clip every second to play.

it's simpler to just run the script every 3-4 seconds instead
