Medical Radiation Doses on the Rise
A study presented at the annual meeting of the National Council on Radiation Protection & Measurements, found that U.S. residents have experienced a sixfold increase in medical radiation dose since 1980 -- with much of that increase due to CT scanning.  Indeed, CT scanning accounts for 45% of the medical radiation dose delivered in the U.S., despite making up just 12% of all medical radiation procedures in the country.

Silica Acid ITLC Paper
Since Silica Acid paper is no longer commercially available from Pall or Varian.  There is a question as to an alternative QC method for Tc-99m Mebrofenin.  Jim Ponto has forwarded a Disofenin QC procedure that can also be applied to Mebrofenin.  If you are aware of a supplier or alternative QC methods, please post on the nuclear pharmacy eCommunity discussion board or forward to

Pellet of Pu-238

Plutonium-238 (Pu-238) is used by the U.S. Space Program to power missions in space. Radioisotope thermoelectric generators (RTGs) are constructed using marshmallow-sized pellets of Pu-238. As it decays, interactions between the alpha particles and the shielding material produce heat that can be converted into electricity. Two reasons that Pu-238 is used are because of its half-life and decay properties. It has a half-life of 87.7 years. This means that after five years, it is still generating about 96% of its original heat output. Also, because Pu-238 decays mainly by alpha decay, only lightweight shielding is required. These two properties make it ideal for use in space.
