Risk Estimation of Carcinogenic and Noncarcinogenic Diseases from Radiation for Medical X-ray Workers.

The objective of this paper is to construct a follow-up cohort of medical x-ray workers and analyze the risk estimates of radiation-induced carcinogenic and noncarcinogenic diseases induced by chronic low-dose ionizing radiation exposure in the follow-up cohort. A fixed cohort study was used. A total of 159 medical x-ray workers working in radiology departments of hospitals in Gansu Province from 1950 to 1980 were selected as the radiology group, and 149 medical workers in internal medicine, surgery, and other departments who had not engaged in radiology work at the same hospital were selected as the control group.

Chromosomal aberration analysis: Novel noninvasive techniques for early-stage cancer screening.

Objective: Chromosome breakage is a catastrophic event that leads to the progressive development and progression of cancer. In order to analyze the changes of peripheral blood microenvironment of tumor patients, to explore the indicators of non-specific non-invasive tumor early screening. This paper presents a new idea of whether the gene sequence near the DNA damage break point is the gene sequence that controls the unrestricted growth of normal cells.

Thyroid dose assessments due to inhalation of I for nuclear medicine workers.

Background: In general, medical staff who work in nuclear medicine should be entirely safe in their professional environment. Nevertheless, we already know that the working environment of the nuclear medicine staff is not completely safe due to the handling of high amounts of radionuclides for diagnostic and therapy applications, which is especially relevant for I (as a non-sealed source).

Purpose: The goal of this study was to assess the inhaled I thyroid dose in nuclear medicine workers and to introduce a simple method for internal exposure monitoring.

Revision of cytogenetic dosimetry in the IAEA manual 2011 based on data about radio-sensitivity and dose-rate findings contributing.

In order to achieve the goal of rapid response, effective controland protection of life inlarge-scale radiation events, the IAEA Manual 2011 has been revised based on the data of radio-sensitivity, dose-rate findings. Analyze individual differences in radiation sensitivity using Co radiation (0.27 Gy/min).

Study of Low-Dose Radiation Workers Ionizing Radiation Sensitivity Index and Radiation Dose-Effect Relationship.

Background: In the present study, we analyzed radiation injuries to Chinese workers exposed to low-dose radiation. We discuss the relationships between dose and injury.

Methods: This study randomly selected 976 radiation workers who underwent occupational health monitoring.
