The executive housecleaning continues at radioisotope developer International Isotopes. The Denton, TX, company reported today that president Carl Seidel is leaving, just days after Ira Morgan stepped down from his position as chairman of the firm. Seidel's duties will be assumed by David Camp, who was named CEO of International Isotopes in November. The company said that the changes are being made to better position the firm as it begins commercial production of radioisotopes.
