[Personal computer interactive algorithm for estimating radiologic contamination and doses after a nuclear accident in Europe].

The algorithm RANA (radiological assessment of nuclear accidents) is a tool which can be exploited to estimate the space and time structure of the radiological consequences of a radioactive release following a nuclear accident in Europe. The algorithm, formulated in the language of Mathematica, can be run on a personal computer. It uses simplified physical assumptions as for the the diffusion of the cloud and the transfer of the contamination to the food chain. The user gets the needed information by means of interactive windows that allow a fast evaluation of dose and contamination profiles. Calculations are performed either starting from the source terms or from the knowledge of experimental contamination data. Radiological consequences, such as individual or collective doses from several exposure paths, are parametrized in terms of the atmospheric diffusion categories.

Immediate femoral sheath removal after 6 French routine coronary angioplasty with a weight-adjusted low-dose heparin: results of a prospective registry.

This study assesses the feasibility and safety of immediate sheath removal after coronary angioplasty with the use of 6 French (Fr) guiding catheters by the femoral route and weight-adjusted low-dose heparin (100 IU/kg). We prospectively evaluated such a strategy among a single-center cohort of 261 consecutive patients undergoing routine percutaneous transluminal coronary angioplasty (PTCA). Immediate sheath withdrawal was performed in cases when post-PTCA residual coronary stenosis was less than 30%, with or without stenting. One hundred eighty-two (70%) of the enrolled patients were eligible for immediate sheath removal. When compared with non-eligible patients (sheath removal 4 hours or more post-PTCA), we observed a reduction of hematoma occurrence (15% vs. 30%; p < 0.01), time to manual hemostasis of the puncture site (13.8 +/- 7 vs. 19.7 +/- 12 minutes; p < 0.0001), and time to hospital discharge (2.2 +/- 1.9 vs. 2.8 +/- 1.8 days; p < 0.02), while ischemic event rate was similar (1 vs. 2 non-Q wave myocardial infarction; 2 vs. 1 repeat PTCA for out-of-lab acute vessel closure). In conclusion, a good angiographic result at completion of PTCA using a 6 Fr sheath, even without stenting, makes an immediate sheath removal feasible at no increased risk and with a potential reduction in minor bleeding complications.

[The Chernobyl incident: dose assessment in Italy and Europe].

The radiological impact of Chernobyl accident on the Italian population has been reassessed on the basis of the activity average values, measured in environmental and food matrices since 1986. The evaluation has been made taking into account the new risk estimates by the International Commission on Radiological Protection (ICRP). Moreover, in order to compare the calculated doses with data from Whole Body Counter and to check models describing the time trend of radioactive contamination, the activity levels systematically measured in the Emilia Romagna district (Northern Italy) were considered. The dose assessment has been compared with the European one made by UNSCEAR (United Nations Scientific Committee on the Effects of Atomic Radiation).

[The Chernobyl incident: emergency management in Italy and other European countries].

Several measures were adopted by European countries in the aftermath of the Chernobyl accident. In this paper these measures are reviewed and the European Communities initiatives for food marketing and exports are analyzed, together with the reference levels for radioactive concentration in the main food matrices chosen in different European countries in the very few days after the accident. A particular attention has been devoted to the emergency management in Italy, outlining exhaustively the laws enforced at the time of the accident and explaining how the reference levels for food contamination were chosen. Finally, a tentative balance about emergency management in Italy is struck and some questions are raised about the commitments undertaken or to be undertaken by international institutions.
