microcurie การใช้

Note : A microcurie ( \ mu Ci ) is a measure of the disintegration rate, or activity, of a radioactive source; it is 2.22E06 disintegrations per minute.
Bailey created Radithor by dissolving radium salts in water to deliver 1 microcurie of radiation from each of 226 Ra and 228 Ra, claiming its curative properties were due to stimulation of the endocrine system.
In 1961 it was reported that Tanner, then an associate professor of zoology and entomology at BYU, was in the midst of a four-year study of the effect on Utah wildlife from exposure to higher natural radiation ( from petrified trees which can concentrate radioactive minerals ), resulting in areas with a 10 to 20 microcurie higher radiation level per hour than is typical of the surrounding geography.
