All of the Generators at the sites I look after (except the smallest sheds) are specced with a day tank (enough fuel for one day) and a bulk tank (enough fuel for 5 days at full load). part of the routine checks is "how much fuel in the tank" and "how much water in the fuel". Most of our diesel is much older than 12 months and is perfectly fine.
Got sent to a report of a customers phone not working. As I approached the address I noticed the main overhead cable hanging low and stopped for a look.
Lightning had hit the cable and blown all the wires out the side of the sheathing.
They were so neatly spaced, it looked like the lightning had got halfway through prepping for a splice joint then gone for a tea break.
As I stood admiring the mess, other repair vans started turning up in response to the 100 customer fault reports.
I passed my job back for attention of the cable gangs and cleared off.
Dictionary definition of Half Life: The time required for half the nuclei in a sample of a specific isotopic species to undergo radioactive decay.
basically, within that time period half of the radioactive isotope has decayed into the next element in that particular chain, leaving half behind.
so after those "hours " are up, there will still be some left to be found, Thats why the iodine with a half life of 8 days will take weeks to decay, not just 1 week and a day.
