Cosmic radiation is only an issue with high speed films. Paper is so slow compared to film I wouldn't be concerned about it. Kodak stores high speed films deep underground in a salt mine near Batavia, NY to minimize the effects of radiation.
Life of paper on the shelf (room temp) is not more than 2.5 years and that is with RC. It is less with FB. Believe it or not, the ID improves life. At least w Kodak papers. Then fog begins to build up.
Dave PS: NYS Riesling goes pretty good with souped Tmax film.----- Original Message ----- From: "mail1" <mail1@xxxxxxxxxxxxxxxxx>

I now remember the rest of the conversation with the Ilford rep. Hementioned that cosmic radiation contributed to the fogging of the paper, andfilm, and that this radiation easily passed through my freezer. He also mentioned the savings in electricity would go towards buying fresh paper. Years ago I acquired a photographer's studio at an estate sale. Among theitems was a freezer of film and paper. I had no idea how long the paper hadbeen in the freezer. I ran the freezer for a couple of years until itfinally died. The paper then lived at cool dead freezer temp for about 6 ormore years, before I tested the paper, and film with a step table. All the RC paper was heavily fogged. I suspected developer was incorporated in theemulsion. The fiber base paper is useable with great care. The biggest issueis the choice of developer and time of development. 1min. to 90sec. maxanything over the later time fogs the paper. The film fared better as I wasable to print through the fog. The Ilford Delta 3200 was a loser. The film is mostly long gone except for some 4x5 B&W, and Color stock. Some paper still exist which I rarely but occasionally revisit when I'm printing a print that does not have bright high lights. One of these days I will have to deep six the freezer, and what remains inside. In the mean time I'm try to use up my fresh stock so that it does not end up in the dead freezer. There is a small amount of film in our small kitchen refrigerator freezer section, and my wife has suggested I might think about cooking it for dinner, and I counter with, it might be better if I soup it.

Options are have the paper go bad as the natural age is used up. If that happens the paper might be used for someartsy stuff. Option two: Possible emulsion freezing and re-freezing issues,that you may never see. I'll go with the later....Please understand, it is always better to buy and use fresh paper and notbuy huge quantities and freeze it. However when you get a gem like old Ektalure, which has been discontinued, there is no option.

I spoke with an Ilford Rep some years ago and he advised against refreezing because of the possible damage to the emulsion. I have not gone the freezer route as energy to run the freezer is costly living off the grid. In fact the last freezer I had ran 100% of the time when the ambient air temp reached 95'which amounted to 5000 watts over 24 hours.

If he tries some and it does not have fog or mottle it is still good. I would keep it in a plastic bag and freeze it. Allowing it to warm up for an hour before using it and re-freezing remainder immediately afterwards.Kodak discontinued Ektalure about 6 or 7 years ago. It is an outstandingproduct with history going back almost 100 years.----- Original Message ----- From: "Janet Cull" <jcull@xxxxxxxxxxxxx>To: <pure-silver@xxxxxxxxxxxxx> Sent: Monday, March 24, 2008 11:09 PM Subject: [pure-silver] Re: Kodak Special PX 3001paperAnd does this mean it will be on the market? or is his an old box?

Then they are selected based on what ever change was madein the product so they might be sensitive to the change. For example, if a change was made that affected how the paper would look in process the users would be selected based on the different chemistries they used. That means the sale reps would really need to know their customer base. Usually all professional photographers. They would test the material and Kodak research staff would interview them.

FX is "film experiment" PX is "paper experiment". The 3001 just means that was the next number availablefrom corporate for test projects. It is a more recent number. Openthe box (in total dark, no safelights) and see if there is a stuffersheet inside. It will tell you how to process the paper and hopefully how to expose it. I don't remember if 3001 was one of mineor not. Dave It's nice to have really authoritative information available to the list.
