More than 500 measurements of the activity (dose) in the lungs of miners were provided in ura-
nium and non-uranium mines of former Middle Asia Republic of the USSR over an 11 year period.
Some of the results are presented in Table 15.5 Measurements took place in June 1969 in Tadjikistan.

Lung Cancer Mortality Data
In order to study the lung cancer mortality of miners, data were collected in Alterman (1974)
about mortality among all male populations older than 19 year in the cities of Tadjikistan
(200,000), a similar contingent of mining settlements (11,000), and different groups of under-
ground workers (2,400) from 1960 to 1970. In this region, 30 mines and geology-prospecting
teams were located.
The primary diagnosis of cancer took place in the health department of the industrial complex.
All such complexes had x-ray diagnostic equipment with special medical personnel trained in the
diagnosis of the sickness of breathing organs. Patients with suspected cancer were directed to the
oncology department (hospitals) in the cities of Leninabad (now Hodjent), Dushanbe, Tashkent, and
Alma-Ata for inal diagnosis.
