This image was published on the photo blog of Takashi Morizumi. It appears Dr. Satoshi Mori was responsible for the x-ray-like view showing black dots spread throughout the body of a small bird from Iitate Village. The dots are said to be radioactive particles of Cs-137 internalized by eating contaminated insects.
