this is posted somewhere, but i'm bringing it back 

https://en.wikipedia.org/wiki/Atomic_gardening

i found irradiated seed packets experiment for sale,

https://www.walmart.com/ip/Irradiated-Seed-Set-Radish-5-Packs-of-50/812469713
"Seed that have been exposed to a Cobalt-60 source are used to demonstrate the effects of varying degrees of radiation. Squash preparations of root tips show distinct disturbances of the normal mitotic pattern. Somatic changes brought on by irradiation are often clearly visible a short time after germination begins. The set contains an untreated control packet and packet of seed exposed to various levels of radiation (50; 150; 500; 4,000 Krads)."

but i'd like to make my own irradiated seeds thank you.. Any ideas for radiation sources?

im not sure it's legal to possess cobalt60 like they used,
but there are sterilization companies who use cobalt 60,
maybe send them a package of seeds to be irradiated...

I would expect that everything going through a sterilization cobalt source be completely dead. I know someone working in such a company, will ask an opinion.

[ONandONandON]

it depends on the amount of exposure time and distance to source.
"exposed to various levels of radiation (50; 150; 500; 4,000 Krads)"

I think you could buy an old X-ray generator, which can be switched on and off instead of continuously emit radiation, however I have no idea how much radiation you'd give to get the desired results.

yep xrays seem too be the most available option..
one could measure exposure to seeds with a radiation detector ~70$
xrays can be created simply by passing a high voltage threw a vacuum chamber like a lightbulb..
xrays from lightbulb utube
Also need something like lead sheets, or water jug containers to block the xrays from hitting you.

Maybe using the americanium 241 cartridge found in the cheap smoke detectors? Those are alpha rays but if the seeds are close enough maybe they can mutate it
.

Strong sunlight alone on seedlings freshly germinated can also cause mutations. The mutation rate isn't the highest though... other things that can be done are freezing conditions for seedlings 5min or so and just general abuse like drought as very young seedling.
