Oct. 23, 2009 — A mathematical model constructed by researchers at Imperial College London predicts the risk of cardiovascular disease (heart attacks, stroke) associated with low background levels of radiation. The model shows that the risk would vary almost in proportion with dose.
Results, published October 23 in the open-access journal PLoS Computational Biology, are consistent with risk levels reported in previous studies involving nuclear workers.
Cardiovascular disease is the leading cause of death and one of the leading causes of disability in developed countries, as reported in the paper and also by the World Health Organization. For some time, scientists have understood how high-dose radiotherapy (RT) causes inflammation in the heart and large arteries and how this results in the increased levels of cardiovascular disease observed in many groups of patients who receive RT. However, in the last few years, studies have shown that there may also be cardiovascular risks associated with the much lower fractionated doses of radiation received by groups such as nuclear workers, but it is not clear what biological mechanisms are responsible.
According to the vice-principal of Minamisoma city general hospital, cerebral apoplexy rate among 35 ~ 64 years old people spiked up to be 3.4 times much as before.
This is the statement made in the disaster restoration committee at the House of Representatives on 5/8/2013.
The vice-principal, Oikawa is a neurologist.
He stated he’s collaborating to collect the data about the crisis rate of cerebral apoplexy with Tokyo university. The provisional data says the crisis rate of cerebral apoplexy among 35 ~ 64 years old people in Minamisoma area is 3.4 times much as before. The rate among over 65 years old people is 1.4 times much as before.
He said this is an extremely scary data.
