claim: a photograph shows a group of daisies that mutated due to radiation from the fukushima nuclear power plant.
question: are mutated daisies growing near fukushima?
origin: although many viewers assumed that the mutations displayed in the photograph (taken in nasushiobara city) were caused by nuclear radiation from the fukushima power plant, which experienced a catastrophic meltdown following a tsunami in march 2011, that may not be the case.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  on 27 may 2015, twitter user @san_kaido uploaded a photograph purportedly showing mutated shasta daisies growing near the fukushima nuclear power plant in japan:
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  translation: “the right one grew up, split into 2 stems to have 2 flowers connected each other, having 4 stems of flower tied beltlike. the left one has 4 stems that grew up to be tied to each other and it had z ring-shaped flower. the atmospheric dose is 0.5 μsv/h at 1m above the ground.”
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  @san_kaido claimed in the tweet that the radiation level near the daisies was measured at “0.5 μsv/h at 1m above the ground.” this is only slightly above normal and is classified as safe for “medium to long term habitation.”
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  furthermore, daisies showcasing similar mutations have been found at locations far away from nuclear radiation. this photograph, for example, was taken in 2010 in the dutch nature area de groesplaat, in north brabant:
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  and this photograph was taken in a cow pasture in island park, idaho, in 2010:
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  in fact, the appearance seen in the photograph depicting mutated daisies near the fukushima plant may simply be the result of fasciation, not nuclear radiation:
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  more often than not, a flower which is affected by fasciation can be identified by a variety of common problems or mutations, if you will. flower stems can appear much flatter and wider than the average plant and some may even have more flower heads than expected.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  whilst it’s an extremely rare condition for plants to have, it has been recorded in over 100 different types of plant across the world and it probably affects many more which haven’t been found yet. due to the rarity and the strange cases that can result from fasciation, some people have been known to grow prize winning flowers with this disorder thanks primarily to deformations that actually enhance the look of the plant.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  there is no one single cause for fasciation as some people are led to believe. instead, there are a variety of factors that can cause a plant to become fasciated and these have been listed below:
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  hormonal imbalance — having a hormonal imbalance can have an impact on certain cells in the plant where growth mainly occurs. because of the imbalance these cells do not grow or develop properly like they would in a regular plant.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  infections — plants can be fouled by viral or bacterial infections which go on to take over the plant and cause mutilations [sic]. certain bacterium has been linked with plants which have fasciation, but by no means is it exclusive to every plant that has the problem.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  genetics — just like in humans, genetics play a huge role in the structure of the body and a plant is no different. whilst there are no specific causes for genetics to be altered or predisposed to certain plants, it is simply considered to be a random mutation in the genetics of a plant.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  environment — the environment that the plant grows in can also play a huge role in the things that come into contact with it. insects and animals attacking the plant and causing damage can both lead to fasciation; same as fungi or mites. harsh chemicals used to get rid of pests may also cause problems, as well as exposure to harsh weather conditions in winter like frost. many of these can be a factor in causing fasciation.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  while radiation from the fukushima disaster in 2011 certainly has had an impact on the plant life in the surrounding area, the above-displayed photograph doesn’t necessarily show the mutation of daisies due to nuclear radiation. it is much more likely that this image simply displays an example of fasciation.
