Abstract Evaluation of data on the frequency of severe mental retardation among prenatally exposed survivors of the atomic bombing of Hiroshima and Nagasaki, and the performance of such survivors on intelligence tests and in school has shown the most striking effects on the developing brain of exposure to ionizing radiation to occur among those individuals exposed in the 8th through the 15th, and the 16th through the 25th week after fertilization. This is true under the earlier T65DR and the… Expand

Threshold for radiation-related severe mental retardation in prenatally exposed A-bomb survivors: a re-analysis.
TLDR
The distribution of cases of severe mental retardation suggests a threshold in the low-dose region, and the 95% lower bound of the threshold in those survivors exposed 8-15 weeks after ovulation was zero for the individual data based on the simple linear model, and 0.05 Gy using the maximum likelihood estimates derived from an exponential-linear model. Expand
Developmental abnormalities induced by ionizing and nonionizing radiation
TLDR
Embryos are more susceptible to ionizing radiation than adults and there is no evidence of human congenital abnormalities caused by nonionizing radiation, but some studies have reported effects of radio frequency and extremely low‐frequency electromagnetic fields on cell proliferation and differentiation. Expand
Radiation-related small head sizes among prenatally exposed A-bomb survivors.
TLDR
A significant effect of radiation on the frequency of individuals with atypically small heads is observed only in the first and second trimesters and for the intervals postovulation of 0-7 weeks and 8-15 weeks. Expand
Radiation‐Induced Apoptosis and Developmental Disturbance of the Brain *
The developing mammalian brain is highly susceptible to ionizing radiation. A significant increase in small head size and mental retardation has been noted in prenatally exposed survivors of the… Expand
A longitudinal study of growth and development of stature among prenatally exposed atomic bomb survivors.
TLDR
The relationship between birth weights and repeated measurements of stature in adolescence is discussed based on the results obtained by a growth curve analysis. Expand
Psychophysiologic aftereffects of prenatal irradiation.
TLDR
The data obtained reveal mental disorders in prenatally irradiated children and obviously reflect developmental abnormalities of brain structure and function as a result of the interaction of prenatal and post-natal factors where it is possible to assume radiation effects on the developing brain. Expand
In utero exposure to low-doses of ionizing radiation decelerates neuronal migration in the developing rat brain.
TLDR
The findings suggest the possible role of N-CAM in neuronal migration and also suggest the presence of a threshold in terms of the effects of small radiation doses on the developing cerebral cortex. Expand
Evidence of radiation-induced reduction of height and body weight from repeated measurements of adults exposed in childhood to the atomic bombs.
Reduction of growth from exposure to atomic bomb radiation has been examined using individuals under 10 years old at the time of the bombing (ATB) and a growth curve analysis based on measurements of… Expand
This Is Only a Test? Long-Run and Intergenerational Impacts of Prenatal Exposure to Radioactive Fallout
Abstract We examine the effect of radiation exposure in utero, resulting from nuclear weapon testing in the 1950s and early 1960s, on long-run outcomes of Norwegian children. Exposure to low-dose… Expand
Long-Run Impacts of Prenatal Exposure to Radioactive Fallout 1
Research increasingly shows that differences in endowments at birth need not be genetic but instead are influenced by environmental factors while the fetus is in the womb. In addition, these… Expand

Prenatal exposure to ionizing radiation and subsequent development of seizures.
TLDR
The incidence of seizures was highest with irradiation at the eighth through the 15th week after fertilization among subjects with doses exceeding 0.10 Gy and was linearly related to the level of fetal exposure. Expand
C. Growth and Development Following Prenatal and Childhood Exposure to Atomic Radiation
TLDR
Harmful effects of radiation later in pregnancy and in early childhood have not been as clearly demonstrated, however reduction in growth is also found among Hiroshima children. Expand
Organ dose estimates for the Japanese atomic-bomb survivors.
TLDR
Investigation of Shielding of internal organs by the body has been investigated for fission-weapon gamma rays and neutrons, and ratios of mean absorbed dose in a number of organs to survivors T65D assignments of tissue kerma in air are provided. Expand
Developmental-stage-dependent radiosensitivity of neural cells in the ventricular zone of telencephalon in mouse and rat fetuses.
TLDR
The highest radiosensitivity in terms of acute cell death was shown in the same developmental stage of brain development, i.e., the beginning phase of cerebral cortical histogenesis, in both mice and rats. Expand

Quantitative growth and development of human brain
TLDR
The growth spurt period is much more postnatal than has formerly been supposed; the cerebellum has special growth characteristics; and there is a separate period from 10 to 18 weeks' gestation when adult neuronal cell number may largely be achieved. Expand
Acute non-stochastic effect of very low dose whole-body exposure, a thymidine equivalent serum factor.
TLDR
The acute low-dose effect of whole-body irradiation of mice causes the dose-dependent appearance of a humoral factor in blood serum which inhibits incorporation of 125-IUdR into tissue culture cells and has implications for the measurement of low- dose exposure by biological dosimeters and on basic research on membrane function. Expand
Acute and temporary inhibition of thymidine kinase in mouse bone marrow cells after low-dose exposure.
TLDR
The reversibility of the effect in vivo and in vitro suggests a particular enzyme control mechanism that may be non-specifically triggered by intracellular charges, such as peroxides, and may enhance repair. Expand

TLDR
Measurements of neuron-specific and glia-specific proteins were used to characterize chemical-induced injury to the rat CNS and indicate that neurotypic and gliotypic proteins may be used to characterized the temporal and regional patterns of neuronal and glial responses to injury. Expand
