The fluence to effective-dose and organ-absorbed-dose conversion coefficients for charged pions and muons were calculated based on the instructions given in ICRP Publication 103. For the calculation, the particle motions in the ICRP/ICRU adult reference computational phantoms were simulated using the PHITS code for four idealized irradiation geometries as well as those closely representing the ...

background: coronary angiography is a commonly performed diagnostic procedure with life saving benefits for the patient. however, this procedure involves relatively high radiation dose. the purpose of this study was to determine the average effective dose of patients undergoing coronary angiography and to estimate the associated radiation risk in terms of fatal malignancy. materials and methods...

One of the essential parameters influencing of the dose conversion factor is the ratio of unattached short-lived radon progeny. This may differ from the value identified for indoor conditions when considering special workplaces such as mines. Inevitably, application of the dose conversion factors used in surface workplaces considerably reduces the reliability of dose estimation in the case of m...

Forty-two piglets on days 3 and 12 of age were used to determine the rate of intestinal absorption of iron by the red cell radioiron method and to evaluate the effect of age on intestinal absorption of iron. s9 Fe-labelled ferric citrate in a dose of 1 2 /aci per kilogram weight was administered with carrier ferric citrate in 5% fructose solution by stomach tube after 1-hr fast. Two levels of c...

Dose-response models are an important part of quantitative microbiological risk assessments. In this paper, we present a transparent and ready-to-use version published dose-response model that estimates the probability infection illness after consumption meal is contaminated with pathogen Campylobacter jejuni . To end, metadata implemented in fskx-standard. The parameter values based on data fr...

Phytol-U-(14)C was adsorbed on algae and ingested in this form by zooplanktonic copepods (two species of Calanus). The lipids of these animals were analyzed after 48 hr and found to contain radioactive pristane and radioactive phytanic acid. The conversion of phytol to pristane by the copepods is interpreted as a likely biological source of pristane in nature.

Phytol-U-14C was adsorbed on algae and ingested in this form by zooplanktonic copepods (two species of Culunus). The lipids of these animals were analyzed after 48 hr and found to contain radioactive pristane and radioactive phytanic acid. The conversion of phytol to pristane by the copepods is interpreted as a likely biological source of pristane in nature.
