The transfer of different forms of 35S to goat milk

Radionuclide transfer to animal products: revised recommended transfer coefficient values

“…In contrast to the statement by Ward and Johnson (1989), a number of authors (see Howard et al, 1989Howard et al, , 1996Howard et al, , 1997Howard et al, , 2007aHove, 1991, 1993;Belli et al, 1993;Assimakopoulos et al, 1994;Beresford et al, 1998aBeresford et al, , 2000 have reported variations in transfer coefficients due to factors including: effect of age/body weight; physiological status; associated stable element status; and physicochemical form (including the ingestion of soil-or sediment-associated radionuclides).…”

Quantifying the transfer of radionuclides to food products from domestic farm animals

“…The use of concentration ratios for radioisotopes of the macro-elements S, H and C rather than transfer coefficients has been suggested by Howard et al (2007) and Galeriu et al (2007) as the elemental contents of meat and milk do not vary significantly with factors, such as milk yield and live-weight, which influence dry matter intake rates and hence estimated transfer coefficients.…”
