Iridium-192 (symbol 192 Ir) is a radioactive isotope of iridium, with a half-life of 73.827 days. [1] It decays by emitting beta (β) particles and gamma (γ) radiation. About 96% of 192 Ir decays occur via emission of β and γ radiation, leading to 192 Pt. Some of the β particles are captured by other 192 Ir nuclei, which are then converted ...
The following awards are administered through the P.R.A.Y. and may be worn on the uniform upon completion of the program. [4] The emblems and awards given to girls at the completion of the program are worn either "in a single horizontal row on the right side of the uniform blouse, level with the Girl Scout Membership Pin [on the uniform sash], or on the vest in the area below the membership ...
Iridium-192 (symbol 192 Ir) is a radioactive isotope of iridium, with a half-life of 73.83 days. [11] It decays by emitting beta (β) particles and gamma (γ) radiation. About 96% of 192 Ir decays occur via emission of β and γ radiation, leading to 192 Pt. Some of the β particles are captured by other 192 Ir nuclei, which are then converted ...
The Eclipse Investigators will study the total solar eclipse at a Girl Scout camp near Erie, which is within the “path of totality,” or where the moon will completely cover the sun during the ...
To earn the patch, girls and adults must attend or make an interfaith presentation about religious awards, then fulfill a personal commitment of their choice that fulfills their "duty to God" as promised in the Boy Scout Oath, such as promoting, earning, or helping another girl earn the religious award for her faith.
Girl Scouts from Western Pennsylvania are among the volunteers collecting scientific data for the Dynamic Eclipse Broadcast Initiative.
is not widely used for industrial radiography as other nuclides, such as cobalt-60 or iridium-192, offer higher radiation output for a given volume. Iodine-131 is another important gamma-emitting radionuclide produced as a fission product. With a short half-life of 8 days, this radioisotope is not of practical use in radioactive sources in ...
Girl Scout says it's the only solar-powered fridge on the East Coast Massey said a huge factor in the project was that the fridge needed to be sustainable, which meant creating a product that was ...
