However, it is important to note that this study is based on internal BPA concentrations at par with those used in commonly used mammalian models equivalent to occupational exposure levels of 2 ppm [ 14, 15].
These results, added to the recommendations of the International Commission on Radiological Protection, which lowered their former occupational equivalent dose limit for the lens, led us to assess the eye lens dose, Hp(3), during interventional procedures.
Because at the end of the day, you're mapping out a journey, and you want whomever will listen to take that journey with you -- or at least you want them to understand why you have just boarded the occupational equivalent of "Mr. Toad's Wild Ride".
The occupational therapy equivalent in Canada refers to a related role as "change agent" [ 38, 39].
Third, the physical activity measurement consisted of a single question and did neither allow calculation of metabolic equivalent of task nor included occupational exposure.
4 Exposure to benzene would increase the risk of AnLL at levels of ≥40 ppm-years of occupational cumulative exposure, equivalent to a lifetime (76 years) environmental exposure of ≥120 ppb.
As to the utility of SOC HE 2010_EP, it is also a disadvantage that we do not have equivalent, commensurate classifications available for earlier occupational codes before SOC2010, which would be needed for long-term trend analyses.
Since then, the Faculty of Occupational Medicine of the Royal College of Physicians commissioned the development of equivalent multi-disciplinary guidelines for the occupational setting [ 22, 23].
We then undertook an in-depth study of the demographic and labour force characteristics for five countries for which time-trend data were available at the four-digit ISCO-88 occupational classification level or equivalent.
Dose limits for occupational exposures are expressed in equivalent doses for deterministic effects in specific tissues and as the effective dose for stochastic effects throughout the body.
