Active methods of remote detection of radioactive anomalies in the atmosphere, including methods employing the effects arising from the interactions of laser radiation with the products of radiolytic decomposition and at photochemical reactions among atmospheric constituents, are analyzed. The results achieved in developing passive remote technologies for monitoring radioactive pollution due to industrial wastes releases into the atmosphere are considered briefly along with the method of laser-induced breakdown of aerosols. The technologies under consideration are shown to be promising in ecological monitoring of radioactive pollution of the atmosphere. High sensitivity of the methods allows pollutants to be detected from long distances. Simultaneous use of the passive and active methods provides for acquiring more information on the radioactive anomalies examined.
