[Medical certificate in psychiatry: practical aspects].

Among certificates written in psychiatry, some are obligatory, admission certificate, in case of automatically hospitalization or that asked by a third party, certificate of 48 hours: in which the psychiatrist of the admission' service describes the state of the patient and indicates the necessity or not to continue the hospitalization, monthly certificate: to justify the maintenance of hospitalization or to ask its end and certificate of situation be written in some particular circumstances. Others concern the cases of expert appraisement (in civilian or penal rights) or in the framework of medical controls asked by the employer. Other certificates are optional or customary. They could be delivered if asked by the patient. These considerations incite to follow scrupulously ethical rules and common sense when doing these certificates. Finally, The certificate has always to be given to the patient personally. That will be mentioned down of the document.

Level of natural and artificial radioactivity in Algeria.

A national environmental sampling program was carried out during 1993 to determine natural and artificial radionuclides contents in the (0-15 cm) upper layer of the soil. The main objective was to establish a radioactive reference level in the whole territory, since 131I, 134Cs and 137Cs were detected in most of the analysed samples collected right after the Chernobyl accident (May 1986). Soil samples were analysed by direct counting by gamma-ray spectrometry. In addition, terrestrial gamma-ray dose rates in air have been measured out of doors throughout Algeria. In each of the 48 administrative divisions of the country selected sites were chosen to collect soil samples and measure gamma-ray dose rates. The gamma-emitting radionuclides resulting from the radioactive decay of 238U and 232Th, 40K and 137Cs were detected in most of the analysed samples. Radioactivity concentrations in Bq kg-1 dry mass in soil samples of 226Ra, 214Pb, 214Bi, 212Pb, 228Ac, 40K and 137Cs range between (5-176), (2-107), (3-65), (2-97), (3-144), (36-1405) and (0.3-41) respectively. In addition, six selected soil samples were analysed to determine plutonium isotopes contents. Radioactivity concentrations in Bq kg-1 dry mass of 238Pu and 239 + 240Pu vary between (0.012-0.013) and (0.24-0.61) respectively. The dose rates in air measured over the whole country were found to range between 20 and 133 nGy h-1. Presence of 137Cs has been clearly observed. An approach has been made to determine its origin, considering the global fallout, the Chernobyl accident and the French nuclear bomb tests in the 60s as the main potential sources. It is concluded that Algeria has indeed been affected by the Chernobyl accident.
