Requirements of local data for foodchain modeling
Plants are grouped into four categories: root crops, grains, green vegetables and pasture. For each of these categories, information is required on:
&
(a) location and surface area of production;
(b) if available, interception factor ( of air-borne
radionuclides);
(c) if available, retention factor (of radionuclides deposited on surface of plant) on edible portion before consumption;
·
(d) growing period before cropping;
(e) depth of root zone;
(f) if available, concentration factor (of
radionuclides) between soil and plant.
(g) if available, irrigation rate per unit surface
area.
II. Animals
Animals are grouped into 3 categories : grazing animals, poultry, and marine/freshwater produce.
(i) For each of the three types of grazing animals -
cattle, cow and sheep, the following information is needed :-
(a) size and location of grazing area;
(b) number of animal per unit grazing area;
(c) milk production rate;
(d) mean life of animal;
(e) soil consumption together with grass/feed intake;
(f) weight of muscle in animal;
(g) weight of liver per animal;
(h) inhalation rate of animal;
