scale by bombardment with neutron.. This work established the fact that
uraniua-235 and uranium-238 fission upon bombardment. In 1940. h o m w ,
evidence obtained proving that uranium can undergo trmnmautation to
new elements higlwr la the atoaic scale. This « u followed by the die-

formation of the Advisory Coamittea oa Uranium. With the organisation
of the National Defense Research Committee* nuclear physics researoh oa

The Manhattan Engineer District was organised and assuoed over-all

differed from the usual procedure because the urgent military need fcr

research end pilot plant studies prior to design and oonetructlon of
the large scale production plants. Ihe research program was conducted
under the auspices of the Metallurgical Laboratory at the University of

SECT 10# 2 - EARLY DEVELOPMENTS
2“U ^ ural R*dlo»otl7lty. - "natural radioactivity’** was dia-
ooverad in 1896 by 3. Becquercl* He had wrapped a bit of a uranium
salt in black paper and placed it near a photographic plate with a
sheet of silver between the aalt and the photographic plate, ifter a
few hours a distinct photograph!* effect m m observed which indicate*
that the uranium salt gave off setae radiation sufficiently penetrating
to pass through the silver plate and affect the photographic emulsion.y
Subsequent experiments with different salts of uranium proved that the
emission came fro* the uranium* This work was followed lay the iso*
lation of radium by P* Curie and H* Curie in 189* and the discovery
that thorium, polonium, raditas* and actinium also gave off penetrat*
ing radiations* A great many substances were later found to be radio*
active, but practically all of these appeared to come originally Stem
either uranium or thorium* Subsequent work proved that three series
of naturally radioactive elements exist* The starting materials,
uraniiu&-2$®, uraaium>»288# and thorium, disintegrate naturally, forming
radioactive elements lower in the atomic seal** This cycle Is re*
peated until stable isotopes of lead are fcrmsd as the final products
of all three series* The flret general theory of radioactive trans
formations, that the disintegration of an atom is accompanied by the
omission of a single "alpha particle"* or "beta particle,"* was pro-
posed by 2* Rutherford and F* 3oddy in 1901*
artificial Disintegration*"* • The conversion of one ele»»

activity of a radioactive substance decreases te half of Its
Initial value. It varies from 1 x 1010 years for thorium te
OmOOt seconds for one isotope of aotiniue*
ffeptunlum. - Neptunium is the chenical element of atcade number 9&i
It is manufactured in the Hanford process and deoays te ths
Hanford product, plutonium*
Pile* m A term used to describe the unit consisting of a lattice ar
rangement of cylindrical pieces of uranium metal and a light
weight material, usually graphite, such that the proper conditions
for the continued fisaion of the uranium sure obtained with the
aubsequent production of plutonium.
Pilot Plant* - A pilot plant is a saall*soale production plant, used
experimentally for research aad to detonaine th# boot deaign for
large-aoale production unito.
Plutonium* • Plutonium la tho chemical eleraent of atomlo number 94*
It Is tho >roduot of tho Hanford process and constitutea the ond

Proton. • Tho proton ia * sub-atomic partiole and ia one of tho con*
atituenta of every known substance* Brotona *re associated with
nautrona to font tho nucleus of each atom of every chemical
element except hydrogen, the nuoleua of which contains only one
proton* Th* number of protona in tho nuoleua identifiea the

tegration of elements aooompaniod by the emission of raya*
Haturai radioactivity is sheen usually by element* of atomie

Separation Chemistry* - The term separation chemistry refere to the
study of the ohemiatry of tho varioua proeeaaea for the separa

Slow • Slow neutrons, al*o oailed thermal neutrons* are those
of 1sweat velocity and energy. They are captured raore readily by
nuclei of uraniua and plutoniuai than are neutron* of any other
velocity and energy.
