the problem with some parts of the article is that in the hard high level contaminated parts we have small animal populations and in the exclusion zone parts not highly contaminated we increasing animal populations coming form other areas. Without some way methodology to weigh or readjust the numbers with new weights any study will generate error prone conclusions. Not only that but when an animal has a shorter life-span due to radiation where do the effects show up? Its not showing in the population increase as the dying happens after the animal has given its maximum number of offspring as the study is studying long-term radiation effects from long-term radiation.
