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.
