... therefore give off more or less radiation, producing a dark or light area on the image. 10. The time taken for the decay of one-half of the original sample of atoms is called the half-life of a radioactive material. 99mTc’s radiation is reduced by half with every 6-hour period. 11. High activity and ...

Radioactivity and man
... Since his appearance on Earth, man has been exposed to natural radiation to which he has adapted perfectly. The dose of natural radiation to which each living organism is exposed every year is about 2.4 mSv. This natural radiation comes from two sources: the Earth, deriving from radionuclides presen ...

Stable Vs Unstable Isotopes
... For lighter atoms, a 1:1 ratio of neutrons to protons is stable For larger atoms, it takes a greater number of neutrons to maintain stability Beyond atomic number 83, all atoms are radioactive (unstable) We call atoms that are radioactive radioisotopes. ...

ICRP Guidelines: `the effective dose equivalent from all sources
... ICRP Guidelines: ‘the effective dose equivalent from all sources, excluding background radiation and medical procedures, to representative members of a critical group, should not exceed 1 mSv in any one year; effective dose equivalents of up to 5 mSv are permissible in some years provided that the t ...

Background radiation
Background radiation is the ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources.Both natural and artificial background radiation varies depending on location and altitude.
