What is curious about the media response indicating the different levels of radiation dosages is their lack of any explanation as to the difference between alpha, beta and gamma radiation sources. After watching CNN with Anderson Cooper and Sanjay Gupta explaining to everyone why rad bunny suits used by nuclear power station workers were being used to stop gamma radiation, I thought even medical doctors (brain surgeons) don't understand the basics of schoolboy nuclear physics. Gupta should have known better.

An alpha radiation source (such as Plutonium) sitting on a desk 1 metre away will not register on a Geiger Muller tube counter. Does it means that is safe to spread on a peanut butter sandwich as apposed to the fore mentioned banana.

Nowhere in the linked article is Relative Biological Effectiveness taken into consideration. No where on any news media either let alone the mention of MOX fuel used at the Fukushima plant.

Again the RBE factor is hugely important and will radically skew the simplistic rad dosage scale shown on your link especially when it comes to human health hazard.

It would appear that everyone and his grandmother who earns their living from the nuclear industry is attempting to downplay the seriousness of the exposure to the release of long term toxic radionuclide isotopes into the environment.

Maybe the article should have calculated the radiation dose of the 10 day round trip to the moon as well.
