All that said, organizations using these techniques might want to be quiet about it because people seem to freak out any time you mention radiation/chemicals/mutations. yah, I haven't mentioned it to the guy from UC that is helping me get seeds and look for grants and places to rent land for the later years of the project, when I will need more space. I am concerned that he or the people who I am asking about the land rentals will freak at the mention of radiation and mutation. eventually, I will probably come up on a direct question or a renters agreement of some kind. then my dedication to honesty might bite me in the ass. |

starbuckwhy - no need to mention it. X-rays of course do not leave any lasting danger/radiation, so at the point you are renting land it's simply a plant breeding project. End of story.

what kind of bulb did you use? |

what kind of bulb did you use? Two germicidal UV-C bulbs, something like these. |

Two germicidal UV-C bulbs, something like these. the link didn't work. i was curious about fitting type (bi-pin?), filament type (fluorescent, led, incandescent) i found one that seems to be some kind of incandescent, seemed weird to me. and the power consumption. |

That link is indeed funky somehow. After fiddling with it i got it to work for me. Try copying and pasting this in manually: www.topbulb.com/gpx9-bulb-9w-t4-germicidal-lamp-uv-c-g23-2-pin-base-clear-glassthe one he linked to is obviously not an LED. And is some sort of two prong bulb. you had mentioned x-ray bulbs are easy to obtain. After briefly googling for some the best i could find are called "collimator" bulbs meant for dentists. I guess Collimator means a highly focused or directed beam. I would think a non-collimated x-ray bulb would be best, but perhaps any would do in a specially designed x-ray seed chamber. Perhaps line the inside with metal to reflect the x-rays all around the inside? No idea what kind of x-ray bulbs are used for bone x-rays. |

That is indeed a strange link error. I used two bi-pin 9-watt fluorescent bulbs. Somewhere I read that roughly 4 watts of the output from each bulb is in the UV-C range. Life and all it brings has kept me from doing the experiments yet to see if the output is sufficient for what I need.

Yeah, sitting in the dentist's chair last week I wondered if a tame dentist would zap a seed packet for a modest fee. hmmm, dentist...modest fee...I guess not...

I just stumbled upon this thread, and man. This is The Most Awesome Thing Ever.
Although I like electrical engineering, figuring out the x-ray dosage for various seeds seems like a long painful trial-and-error. More of a colchicine girl myself. If I was to do this. Which I am not. At the moment.
(But I have been tempted.)

Has anyone got any papers regarding x Ray dosage rates for any seeds? If I have some numbers I could chat with a radiographer mate and see whether it might be achievable when they do machine warms ups and tests...

Steve1, you could just wing it. just use seed that germinates quick so you can easily test. If you need seed, I've got buckets of lettuce, basil, leek, parsnip and carrot that I'm unlikely to use before it goes off. Quick germ test before you start, then make up some little packets, get 'em zapped, then see if anything germinates afterward.

Hmm, I seem to have a small truck load of peas... But am unenthused as I know the dose on this equipment that causes reporting for cancer risk. It's a very, very long time with admittedly low dose gear. We are talking very expensive gear, and if it can't be done with warm up and safety check screenings I couldn't ask.

Next time I'm going to my dentist for routine stuff, I'll ask in advance whether he needs x-rays (I often refuse his request, seeing no reason, on a routine basis); if it appears so, I'll take a baggie of various to put on top of the lead apron, near my chin; no cost to him, eh?

steev would be the same as getting on a long haul flight - not much at all. starbuckwhy - Thanks for the papers, will look them over and post back thoughts...
