But in an emergency move, that became legal in March, the government has increased the permissible dose for nuclear workers from 100 to 250 millisieverts.

In two seconds he received, by the generous standards of the time, a full day's permissible dose of neutron radiation.

The other with the maximum permissible dose on its label, and the names of counteracting substances which would neutralize it.

The eye lens seems to be the most sensitive organ to beta radiation, even in doses far below maximum permissible dose.

The maximum permissible dose of IMO that does not cause gastric disturbance is estimated at 1.5 g/kg body weight, which is higher than for any other sugar substitute.

But radiation levels in the vault area, where the radium is stored, are currently so high that a worker could remain there for only 2.3 hours before exceeding the yearly permissible dose.

However, the maximal permissible dose for the hands is reached after just 2.4 hours or even less, as the volume is usually much less than 1 ml and the quenching therefore smaller.

The maps revealed radiation levels of more than 125 microsieverts per hour at 25 kilometers northwest of the plant, which means that people in these areas were exposed to the annual permissible dose within eight hours.

At one point it indicated he was absorbing radiation for less than a minute at a rate of 500 roentgens an hour (the maximum permissible dose for nuclear power plant operators is 5 roentgens a year).

This report by the NAS from 1967 did not recommend "permissible doses" for space operations, noting the possibility that such limits may jeopardize the mission, but instead estimated what the likely effects would be for a given dose of radiation.

In the second change, the new law calls for establishing a maximum permissible dose of radiation that any individual may receive as a result of leaks from Yucca Mountain but does not mention a limit on the total dose to the population.

The Environmental Protection Agency says the new policy is too lenient and plans to issue a rule in two years that could override portions of it, adding stricter criteria on the maximum permissible dose from material recycled or disposed of without controls.

Not a Serious Health Threat A Labor Department spokesman said that state inspectors who visited the one-story factory on Tuesday and Wednesday found gamma ray radiation from a window measuring 65 millirems per hour, more than 30 times the permissible dose.

Following the generally accepted human permissible dose levels and parameters of the International Committee on Radiological Protection, about 60 percent of the administered calcium 45 was absorbed (and later eliminated from the body), making the initial effective dose about .5 microcurie.
