[Study on genetic radioresistance of natural Drosophila Melanogaster population from radionuclide contaminated regions of Byelarus].

Over the period from 1998 to 2000 adaptation to unfavorable ecological factors was revealed to be formed in natural Drosophila melanogaster populations from various regions of Belarus with increased radiation background due to the Chernobyl accident. This adaptation was shown to be of non-specific character, since the populations from radiation regions were more resistant to the effect of not only factors of physical nature (irradiation), but also to that of chemical mutagen ethylmethanesulphonate. Assessment of population resistance was carried out by means of tests of dominant lethal mutations and recessive sex-linked lethal mutations.

HEPATOMAS IN MICE: INCIDENCE INCREASED AFTER GAMMA IRRADIATION AT LOW DOSE RATES.

Irradiation of LAf(1) mice with gamma-rays (total doses of 618 to 1335 rad) at a rate of 1.45 rad per hour markedly increased the incidence of hepatomas and ovarian adenomas, compared with incidence of these tumors in mice irradiated with x-rays at 30 rad per minute. This was somewhat unexpected, since chromosome aberrations in the liver cells were less frequent after irradiation at the low dose rate. Other types of tumors were not increased by irradiation with gamma-rays at the low dose rate. It is suggested that indirect hormonal mechanisms may contribute to the production of the hepatomas as well as of the ovarian adenomas.

Patient doses and risks from diagnostic radiology in North-east Italy.

A study has been conducted to asses the impact of radiological practice in 1983 in Friuli-Venezia Giulia, a region of North-east Italy with 1,250,000 inhabitants. The design involved three phases: a region-wide frequency survey; dosimetric measurements on patients in all public X-ray facilities; derivation of organ doses from those measurements. Frequencies by type, age and sex and values of the main technical parameters of radiological examinations are presented. Organ doses, effective dose equivalents and risk estimates are given for 14 selected examinations. The annual per-capita effective dose equivalent and the genetically significant dose are estimated at 0.848 mSv and 0.253 mSv, respectively. From these values, collective risks have been predicted by using the risk factors given in the International Commission on Radiological Protection Publication 26. The results indicate that 14 persons risk induced malignancies and 2.5 persons risk genetic detriment.
