Chem- Nuclear Radiation

A particle identical to a helium nucleus produced in a radioactive nucleus

alpha particle

the time required or one half of a radioactive sample to undergo radioactive decay

half life

a unit of radiation measurement equal to 3.7 times 10 ^10 disintegrations per second

curie

a process in which large nuclei split into smaller nuclei with the release of energy

nuclear fission

a nucleus that spontaneously emits radiation

radioactive nucleus

How to minimize the amount of radiation received if you work with a radioactive substance.

Wear personal protection equipment, don’t stay near radiation for to long, and stay away from radiation

Ci

curie

Bq

becquerel

Fission

the splitting of the atom by the release of large amounts of energy.

Fusion

two or more nuclei combined to form a heavier nucleus and release a large amount of energy

alpha particles are composed of

protons and neutrons

gamma radiation is a type of radiation that

is most dangerous

the charge on an alpha particle is

+2

beta particles formed in a radioactive nucleus are

protons and electrons

the skin will provide shielding from which

alpha particles

radiation can cause symptoms like

nausea, a lower white cell count, fatigue, hair loss

radioisotopes used in medical diagnosis have what?

have short half lives, locate in specific organs, emit only gamma rays, produce nonradioactive nuclei

the time required for a radioisotope to decay is measured by its

half life

the fusion reaction occurs

in the sun, forms a larger nuclei from smaller nuclei, requires extremely high temperatures, releases a large amount of energy

what is nuclear radiation

the energy released in form of high speed particles emitted from the nucleus of an unstable radioactive atom
