A-bomb's Major Effects

CURRENT EVIDENCE FROM ABCC/RERF STUDIES FOR LATE HEALTH-RELATED EFFECTS OF RADIATION(B)

Association with atomic bomb radiation	STRONG Statistically significant results in one or more studies. Questions about potential biases are largely resolved. Risk clearly related to amount of exposure.	WEAK Borderline statistical significance or inconsistent results. More studies may be needed.	NONE No statistically significant effect observed. This may reflect a true lack of effect, or be a consequence of inadequate sample size.
In-Utero Survivors
Malignant Tumors		Total solid tumors	Leukemia
Non-cancer Diseases and Conditions	Microcephaly; Mental retardation; Delays in growth and development; Poorer school performance; Lower IQ		Non-cancer mortality
Chromosomal Aberrations		Lymphocytes

(Notes)

For the children of A-bomb survivors (F1),no effects with statistical significance (including borderline statistical significance) have yet been found in relation to exposure to atomic bomb radiation. With regard to the following effects, it has been confirmed that are no statistically significant relationships with stomic bomb radiation:

Solid tumors; Leukemia; Stillbirth; Major congenital anomalies; Early mortality; Chromosomal abnormalities; Protein variants

This is the table of the results of the studies of the Radiation Effects Research Foundation which summarized the same aspects as those in the previous table concerning the in-utero exposed persons.
The footnote to this table summarizes that there is no evidence of genetic effects among the children of A-bomb survivors.
