    First off, IAAMP (I am a medical physicsist). This is sort of radiation-induced growth stimulus was actually studied extensively in the first half of the 20th century. A great reference for this behavior is a paper published in Human & Experimental Toxicology called "Radiation hormesis: its historical foundations as a biological hypothesis" by Calbrese and Baldwin, which examines the dozens of studies examining the effects of low dose radiation on plants, fungi, and insects - fascinating stuff. Over 2/3 of the studies in this time period showed increased growth with radiation, while the other 1/3 used relatively high doses (which is known to have net detrimental effects). People were actually interested in putting radioactive isotopes in fertilizer to encourage crop growth, but results weren't great and the A-bomb happened... and we all know where the public's perception of radiation went after that. I've got a PDF of that paper if anyone is interested (the online version requires a subscription, I believe).

        Yup, I sometimes feel like I missed out by being born after the golden age of radium enemas. On a more serious note, the concept that low doses of radiation can be beneficial has been a pretty hot topic of debate in the radiological science community lately. There was an incident in Taiwan where radioactive Co-60 (is there really any other kind?) was accidentally recycled into scrap steel that was used in over 200 buildings, giving the occupants low doses of radiation. The standardized incidence ratios (the ratio of observed cancers to expected cancers based on the entire population) in these occupants was on the order of ~0.8, or a 20% reduction in cancer incidence. Also look at studies of cancer incidence between regions of high and low background radiation - rates are lower in high background regions. There are all kinds of problems with these epidemiological studies (confounding factors like socioeconomic status and such), but not always. One study compared 100 years of cancer incidence and mortality data of British radiologists - their life expectancies and cancer rates were significantly than other British physicians (also by ~ 20%). If interested, the Nuclear Shipyard Worker Study also has some very interesting results in this vein. Good, controlled research on the topic of low-dose radiation with respect to humans is hard to come by, however, considering the major stigma attached to radiation. Other than worker and background radiation studies, you've pretty much got to wait until an accident happens.

            They do have ideas why low-dose radiation can be beneficial. One possible mechanism is damage prevention. After irradiation, there is an increase in levels of proteins and enzymes that scavenge reactive oxygen species (ROS) (As a point of reference, the natural level of ROS in the body is about 3 orders of magnitude greater than that caused by background radiation). This response subsequently increases the rate that natural ROS are removed, resulting in a net decrease in damaged DNA in the system. Damag

Isn't that how traditional radiation treatment works? The radiation kills the cancer faster than the healthy cells? Of course what do I know, my knowledge of the low dose radiation issue falls into the 'Yeah, I've heard that before' category.

                Well, it isn't that cancer is inherently less tolerant to radiation, but it is closely related. Basically, cancer is usually more rapidly replicating than the tissue around it so radiative damage to DNA will hurt them faster than surround tissue. This is why radiation is generally a second round treatment following surgery and maybe following chemotherapy depending on the cancer of courses. If you can get most of it my surgery then you don't have to dose the radiation (or chemo) as high...

          This is interesting - I remember reading somewhere (probably Wikipedia) that some poisons actually decrease mortality rates in very low doses, the idea being that your body works to get rid of them and this has some benefits. Alcohol, as far as I understand, was a good example. (I vaguely recall something about a U or J shaped curve, but quick googling doesn't get me much). Assuming this is actually true, would the radiation effect fall into the same category?

            Well, I'm not sure how accurate alcohol testing is since it's typically mixed with other chemicals that can be beneficial or harmful. For instance, the benefits of the antioxidants in Red Wine outweigh the possible detriments of the alcohol when taken in moderation (on the order of half a glass a day IIRC).

          Does this apply to all forms of radiation, or only ionizing radiation. Also is it specific to a certain form of ionizing radiation?

      I doubt it's possible to get living organisms to shorten the half-life of radioactive materials, but fungi that abosrb radioactive materials can be very useful. When radioactive waste contaminates the ground, fungi can extract and concentrate it. The mushrooms can then be harvested for disposal as radioactive waste, leaving the soil in the area less radioactive. Paul Stamets describes it in Mycelium Running (there're good facts in between the hippie/druggie/mystical stuff) describing this and other similar applications of fungi as "mycoremediation".
