Radon (222Rn), thoron (220Rn), and their decay products contribute a major fraction (more than 50%) of doses received from ionisation radiation in public domain indoor environments and occupation environments such as uranium mines, thorium plants, and underground facilities, and are recognised as important radiological hazardous materials, which need to be controlled.
Thousands of variables are examined in this data including basic characteristics, medical history, environment, and occupation factors of parents, and variables related to infants.
There are many different variables to describe socioeconomics, e.g. income, education, environment and occupation [ 24- 26].
Third, the importance of psychosocial working conditions may differ according to the occupational environments and occupations under study [ 62].
Environmental determinants include contaminants present in air, food, water, or soil, as well as the built environment; certain occupations may also result in elevated exposures to chemicals, dusts, and fumes.
Environment-related occupations are also expected to grow quickly relative to the rest of the labor force.
This finding allows us to conclude that symptoms of DES are influenced more by dry environments or occupations that involve intensive use of the eyes, such as prolonged work with documents or at a computer, rather than by exposure to microparticles or organic solvents.
The data generated by programs such as SEER are used to identify geographic and population differences in cancer patterns that point to possible links between cancer incidence and occupation, environment, and lifestyle.
Nowadays, with the rapid growth of China's economic and urban population, a fast, economic land occupation, environment protection way of transport is eagerly needed.
Objective: To examine the association between individual exposures due to occupation, environment and lifestyle on sperm count, we conducted a case-control study among 92 fertile and 73 sub-fertile Caucasian males.
