This study is aimed to evaluate the effects of setup errors on dose distribution for target volume and healthy tissue within the irradiated volume and also critical surrounding organs for breast radiotherapy (RT) using both the tangential field and the field-in-field (FIF) technique. Ten patients with breast cancer were enrolled. For each patients two plans were generated; tangential field plan...

At present, radiation technologies are most commonly applied for sterilization of medical supplies and irradiation food products. The results treatment cannot be fully verified by subsequent non-destructive testing. Therefore, processes equipment used should subject to mandatory validation certification. In this paper, we present the obtained during process radiation-technological installations...

Food irradiation is a preservation process of exposing foods to high-energy rays to improve product safety and shelf life. Red meats, poultry, potatoes, onions, spices, seasonings, fresh fruits and vegetables may be irradiated to prevent growth of food poisoning bacteria, eliminate parasites, or delay ripening and spoilage. Also, irradiation could be used to replace chemical preservatives in fo...

  Eviscerated sea bass, Dicentrarchus labrax were irradiated by Cobalt-60 at commercial irradiation facility at dose of 2.5 and 5 kGy at 2–4°C. The influences of the irradiation on proximate, fatty acid and amino acid composition in cultured sea bass were investigated. Significant differences (P<0.0.5) were found between non-irradiated and irradiated sea bass in terms of moisture, protein, fat,...

The public often must decide between assertions made about food safety through irradiation by advocacy groups and by scientific experts. Herein we discuss the policy implications of experimental results that show how favorable and unfavorable information on food irradiation to reduce risks affects willingness-to-pay to control the food-borne pathogen Trichinella in irradiated pork. The surprisi...

BROWN AND SHOHL [1930] and Watchorn [1930] have shown that large doses of irradiated ergosterol lead to a decreased retention of calcium in rats, in spite of the calcification of certain tissues which takes place at the same time. It has been noted also by Brown and Shohl [1930], Duguid, Duggan and Gough [1930] and by Harris [1930] that the severity of the symptoms of hypervitaminosis D corresp...

Reduction of foodborne illnesses and deaths by improving the safety of poultry products is one of the priority areas in the United States, and developing and implementing effective food processing technologies can be very effective to accomplish that goal. Irradiation is an effective processing technology for eliminating pathogens in poultry meat. Addition of antimicrobial agents during process...

Introduction Radiation-induced bystander effect (RIBE) is a phenomenon in which radiation signals are transmitted from irradiated cells to non-irradiated ones, inducing radiation effects in these cells. RIBE plays an effective role in radiation response at environmentally relevant low doses and in radiotherapy, given its impact on adjacent normal tissues or those far from the irradiated tumor. ...

Background: Due to abscopal effect, cell damage may occur outside of the radiation field and the quantification of this effect is one of the most challenging debates in radiation therapy. The aim of this study was to estimate the abscopal effect induced in non-irradiated tumors quantitatively by means of biological effective dose (BED). Materials and Methods: Breast tumors using 4T1 and MC4-L2 ...
