Barium protection walls, ceiling construction process according to the ratio of protective coating material differences between the manufacturers of radiation protection board, different, this project uses a protective coating and 42.5 # cement according to a certain percentage of the configuration, in addition to adding each ingredient manufacturers dedicated sticky 50kg coalescent 4kg, must be uniformly mixed while stirring, preferably mechanical stirring, increasing the homogeneity of mixes. Before construction, concrete interface need to be dealt with first in accordance with standard plaster (clean up dumped wet slurry, etc.), 1m first lay with ash cake mixes, twice every (depending on weather conditions, spacing about 1 day) will stick mixes Compaction knot on lead glass structure, in order to ensure effective protection against construction error, may be appropriate to paint thickness thicker. This standard applies to a range of 1, the use of ionizing radiation or generate all practical activities of ionizing radiation. 2, the radiation workers and the public to accept all practical activities to be added to ionizing radiation control. Carried out within the range listed above and protection related to the design, supervision, time management, you must comply with the following basic principles. A practice of justification: any exposure to ionizing radiation to practice after a demonstration of radiation protection, or to confirm that the practice is worthwhile radiation protection lead glass, the interests of its ionizing radiation hazards due to social and personal derive phase than is acceptable, if the proposed practice can not bring more than the cost (including the cost of health damage costs and protection costs) of net benefits, not the practice should be introduced. 2, optimization of radiological protection: should avoid all unnecessary exposure; to optimize radiological protection principle, with minimal cost to get the greatest net benefit, so that all the necessary illumination is maintained at the lowest level reasonably achievable. 3. The individual dose limit: Personal suffered radiation dose equivalent shall not exceed the specified limits.
