Human epidemiology is used as a basis for risk estimation for cancer, degenerative, and acute radiation syndromes ), the CNS risk relies most extensively on experimental data with animals for its evidence base.

Within 25 30 days of the explosion, the Red Cross surgeon noticed a sharp drop in white blood cell count and established this drop, along with symptoms of fever, as prognostic standards for Acute Radiation Syndrome.
33.
Eben Byers, a famous American socialite, died of multiple cancers ( but not acute radiation syndrome ) in 1932 after consuming large quantities of radium over several years; his death drew public attention to dangers of radiation.
34.
While such radiation may be harmful given sufficient exposure ( i . e . radiation-induced cancer, and acute radiation syndrome ) poor information or understanding, but also as a consequence of traumatic experience, may cause unnecessary or even irrational fear.
35.
In addition to conventional fatalities and acute radiation syndrome fatalities, nine children died of thyroid cancer, and it is estimated that there may be up to 4, 000 excess cancer deaths among the approximately 600, 000 most highly exposed people.
36.
Conventionally therefore, unmodified absorbed dose is not used for comparing stochastic risks but only used to compare against deterministic effects ( " severity " of acute tissue effects that are certain to happen ) such as in acute radiation syndrome.
37.
Complicating the conflict is the fact that, with the exception of diagnoses of Acute Radiation Syndrome, obvious industrial accidents on site, and a detailed analysis of thyroid cancers among children, assignment of causes of death is a statistical rather than a deterministic process.
38.
The inhabitants of Rongelap and Rongerik Atolls were evacuated by US servicemen two days after the detonation, but the residents of the more distant Utrik Atoll weren't evacuated for three days . Many of the inhabitants soon began to show symptoms of acute radiation syndrome.
39.
This predicted death toll includes the 47 workers who died of acute radiation syndrome as a direct result of radiation from the disaster, nine children who died from thyroid cancer and an estimated 4000 people who could die from cancer as a result of exposure to radiation.
40.
Over a hundred people, including Eben Byers and the radium girls, have received committed doses in excess of 10 Gy and went on to die of cancer or natural causes, whereas the same amount of acute external dose would invariably cause an earlier death by acute radiation syndrome.
