Radiation Exposure. (a) Subject to 19.01 (b), Radiation Therapist 1, 2 and 3, nurses who assist in the operating room implantation of radioactive material, and technicians involved in the operation and maintenance of equipment used in radiation treatment who, in the judgment of the Employer are regularly engaged in duties which expose them to radiation, shall be entitled to an additional week of vacation leave each year.
Radiation Exposure. (a) Subject to Radiation Therapist and nurses who assist in the operating room implantation of radioactive material, and technicians involved in the operation and maintenance of equipment used in radiation treatment who, in the judgment of the Employer are regularly engaged in duties which expose them to radiation, shall be entitled to an additional week of vacation leave each year. This provision shall apply only to persons described in (a), who were so employed in a Saskatchewan Cancer Clinic on March or to whom a valid offer of employment had been made by such date.
Radiation Exposure. In order to minimize radiation exposure to bargaining unit personnel, it will be standard practice to utilize employees outside of classification, other non-bargaining unit employees, or outside contractors, regardless of work schedules of employees in the bargaining unit. Such tasks will be performed under adequate supervision with no intent of reducing regularly scheduled work hours available for those employees on the active bargaining unit payroll. The Company will notify the Union when using people outside their classification or if the Company brings in outside contractors to minimize radiation exposure. The Union will have representation on the ALARA Committee and will be privy to all information used in determining exposure limits.
Radiation Exposure. It shall be the responsibility of Operator to ensure that the Equipment does not operate in a manner which could cause radio frequency exposure levels to exceed permissible FCC exposure levels assuming a worker works within two feet of the Equipment and does not take any precautionary actions to avoid exposure.
Radiation Exposure. The AMI supplier shall ensure that their devices and installations are within the acceptable human exposure limits per international standards/WPC norms and as required for the OPTCL service territory. Please describe. 24 Embedded firmware and software shall be configurable and upgradeable locally and remotely & notification should be sent to HES as well as local device. Please describe.
Radiation Exposure. The Employer recognizes the need to maintain safe working conditions for the employees exposed to radiation. The Employer agrees to be bound by the rules and regulations established by the “Authority Having Jurisdiction” for safety on nuclear projects. Exposure to radiation shall be kept as low as possible. An employee who receives his maximum radiation exposure limits prior to the end of any regular work week (Monday through Friday) will be transferred to other suitable work without loss of pay or he shall be paid wages and fringe benefits for the week as if he had worked a full week.
Radiation Exposure. There will be radiation exposure to the breast(s) resulting from the CE-CBBCT study. The relationship between breast cancer and radiation has been studied extensively. It is known that female breast tissue is sensitive to ionizing radiation [16]. However, risk is highly influenced by previous radiation dose to the breast as there is a linear relationship between dose and risk, although the time intervals between exposures may reduce the cumulative effects. Of significant importance is the age at which exposure occurs. At high doses of 100cGy (1000 mGy), in a young woman, relative risk of developing breast cancer at a later age (typically 35-40 years later), is increased from 1.0 to
Radiation Exposure. There will be radiation exposure to the breast(s) resulting from the CE-CBBCT study. The relationship between breast cancer and radiation has been studied extensively.

However, risk is highly influenced by previous radiation dose to the breast as there is a linear relationship between dose and risk, although the time intervals between exposures may reduce the cumulative effects. Of significant importance is the age at which exposure occurs. At high doses of 100cGy (1000 mGy), in a young woman, relative risk of developing breast cancer at a later age (typically 35-40 years later), is increased from 1.0 to 1.4 (2.0 would be double the risk), which is equivalent to the increase in risk from other factors, such as: nulliparity, early age at first menarche (under age 11 years), and having a very late age at menopause [16]. There is no proof of “statistically significant increases below a dose of about 20 cGy (200 mGy)” … and further, “for exposure after the age of about 45 years there is little evidence that radiation increases the occurrence of breast cancer” [16]. The FDA mandates dose limits for screening mammography, because the benefit of screening mammography lies in the need for annual repeat exams to reap the benefits of early detection. The FDA sets a limit of 6 mGy for a two-view screening mammogram, for a 4.2 cm compressed breast with a 50/50 distribution of fat to glandular tissue [17]. The dose for a CBBCT scan to obtain a CNR of ~8, for a 4.2 cm breast equivalent phantom with a 50/50 distribution, is approximately 5.8 mGy. A CNR of ~8 has been determined to be the level needed for diagnostic adequacy (it is likely that screening dose will be more readily understood from the results of this study). There is no mandate that controls the dose for diagnostic mammography because the benefit/risk ratio is considerably higher in the diagnostic population. Also, the radiologist may require an unknown number of extra mammographic views in order to make a diagnostic decision. The American College of Radiology and the Radiologic Society of North America equates the effective whole body dose of a mammographic exam (0.7 mSv) to about 3 months of background radiation [18]. Analysis based on data from 220 diagnostic patients, which are representative of the range of breast thicknesses and densities found in a female population, has shown that the average mean glandular dose of one CBB...
