After scientistsdiscover& that an (_ atan ofuraniuxnaxldbe split,they also realizedthatfission. could release huge +munts of energy. If a fission bmb could be devel~,weapxsoftrm=ndous explosivepower couldbeprcduced. The weapms potential of fission was as apparent to American nuclear physicistsas to their counm in Nazi Germany.' Because Geman scientists disuvered fission,Hitler semzd to have a si~Lficant headstart on the road to a weapn which could terrorize Eursp an2 perhaps even the United States. Amzrican scientistsorganized them selves into research teams* anurgateffort todevelop an atcLc bmb beforeGemany.

The atmic bcxbs leveled both 2 citiesand ended the war in the Pacific. America now debat& hm tc manage the awesane power of attic energy* The debate'centered on congressionalefforts to create an .agencyto direct nuclear research and developmnt. One of the m* controversialLkueswaswhethertoentrustthe atcm to a civilianor to amilitary wency. Decidbigtoentrusttheatcmto civilians,Congress passed tie Atmic EnergyAct which President Truman signedon August 1, 1946. The Act established a five mnbar axmissiok and assignedto the CZczmissicnall atmic eneqy facilitiesandprogram.
