Drosophila melanogaster males were exposed to homogeneous magnetic fields of intensities of 13,000 to 37,000 Gauss as eggs, larvae, pupae and as adults. Sex linked recessive lethals were scored in chromosomes exposed as spermatozoa, spermatids and as

Induction of sex-linked recessive lethal mutations, heritable translocations and genetic crossing-over were studied in Drosophila melanogaster males treated as adults and as embryos with different concentrations of gaseous DBCP. Adults exposed to 30

Benzene is one of the few chemicals which induces chromosomal aberrations but does not induce point mutations. The most sensitive end point in Drosophila, sex-linked recessive lethal mutations, however, has not yet been studied. Information on induct

The fluorescence quenching of a dioxane-based liquid scintillator, by chloroform, is shown to depend on the LET (linear energy transfer) of the exciting radiation. Fluorescence measurements using α ( 241 Am) and ψ ( 60 Co) excitation are explained

Anticipated use of extremely large magnets in future, controlled thermonuclear reactors and occasional exposures in various occupational and research environments both require that biological effects of these fields be investigated. The genetic effec
