The presence of 2 4 4 Pu (t 1 / 2 =81 Ma) in the early solar system is long established [Nature 187 (1960) 36; Science 172 (1971) 837]. 2 4 4 Pu is also one of a number of isotopes which may be detectable as live radioactivity on earth, originating from the Interstellar Medium (ISM). There has been a recent attempt to measure a ISM isotope signature of 2 4 4 Pu [ApJ 558 (2001) L133]. This rises the question of the presence of an anthropogenic contribution in the environment. In order to better assess the 2 4 4 Pu fall-out on earth, we have started a program at VERA to measure 2 4 4 Pu in surface sediments of Lake Michigan, routinely sampled for 2 3 9 , 2 4 0 Pu measurements. Considerable amount of information on other isotopes exist for Lake Michigan. We have reproduced the expected 2 4 1 Pu/ 2 3 9 Pu and 2 4 0 Pu/ 2 3 9 Pu ratios for the global fallout. The measured 2 4 4 Pu/ 2 3 9 Pu was considerably higher than expected and was therefore most likely the result of contamination. Measurement of samples specifically prepared for the measurement of 2 4 4 Pu will be tried in the future.
