Development of Dose Assessment Code for Accidental Tritium Releases-ACUTRI-

Development of Dose Assessment Code for Accidental Tritium Releases

A computer code ACUTRI has been developed to assess tritium doses to the general public. ACUTRI can calculate the doses for tritium gas (HT) and tritiated water (HTO) accidentally released from the facilities to the atmosphere. The models in this code consist of the tritium transfer model including oxidation of HT to HTO and reemission of HTO from soil to the atmosphere and the dose calculation...

diagnostic and developmental potentials of dynamic assessment for writing skill

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...

Index Method for Cost-effective Assessment of Risk to the Environment from Accidental Releases

The objective of this study was to develop a methodology by which the risk from major accident hazards to the environment can be assessed or quantified. An index method, the Environmental Risk Index (ERI), has been developed based on an existing method, the Environmental Hazard Index (EHI), and the Department of the Environment (DoE) definitions of events that would constitute a major accident ...

Poseidon/rodos Model for Radiological Assessment of Marine Environment after Accidental Releases: Application to Coastal Areas

In the framework of the developments of the European system RODOS for emergency response to nuclear accident (Real-time On-line DecisiOn support System), the computer code POSEIDON, that was developed to assess the radiological consequences of radioactive releases into marine environment, was adapted to cope with emergency conditions, in situations of radioactive discharges into the oceans from...
