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»»

sent into another, the dream of scientists since the earliest days of
