Collective effective dose committed per unit energy generated

In one accident, at Palomares, Spain, the highest committed effective dose was about 200 mSv.

The collective effective dose committed by the accident is estimated to have been about 600,000 man Sv.

The dose referred to is almost always the effective dose.

Absorbed dose, equivalent dose and effective dose all apply to individuals or to average individuals.

Annual collective effective dose a

1.1.2.2.5 In the French version, replace dose effective with dose efficace .

Even if the total collective dose is taken to be 105 man Sv, it is a small fraction of the collective effective dose committed by the test programmes.

Collective effective dose (million man Sv)

Annual average effective dose per monitored worker

The local and regional collective effective dose to the public committed by these operations is estimated to be about 1,000 man Sv.

At low doses with any dose rate and at high doses with low dose rate, only the term proportional to dose is effective.

The unit of effective dose commitment is the sievert.

Patient doses are expressed in terms of effective dose.

The Committee has used a quantity analogous to effective dose, but ignoring the dose to the target tissue.

All these features are included in the selection of the weighting factors for converting equivalent dose into effective dose.

It may refer to the total of the future doses committed by that source or unit of practice, as for instance, the collective effective dose committed by atmospheric nuclear explosions or by one year of medical exposures.

To allow for this, a further quantity, the effective dose, is used.

The unit of collective effective dose is the man sievert (man Sv).

The radiation dose from a nuclear medicine investigation is expressed as an effective dose with units of sieverts (usually given in millisieverts, mSv).

The resulting collective effective dose was not more than about 40 man Sv.

When the relationship is clearly non linear, the quantities can be specified at a stated dose, usually at an effective dose of 1 Sv.

The average effective dose for this group of 1,150 people was about 500 mSv.

It is not possible to make direct measurements of the effective dose to workers.

And I'm very happy to report that we're now using a dose of radiation that is equivalent to the effective dose from one digital mammogram.

The transport accidents caused local contamination by plutonium. The collective dose committed by those accidents is small.

However, to ensure a clear distinction between the absorbed dose and its weighted analogues, it has been agreed that the unit of equivalent dose and of effective dose should have the special name sievert (Sv).

The total collective effective dose committed by weapons testing to date is about 3 107 man Sv. Of this, about 7 106 man Sv will have been delivered by the year 2200.

The Certain Safety Factor is the ratio of the lethal dose to 1 of population to the effective dose to 99 of the population (LD1 ED99).

World wide, the annual effective dose per caput from diagnostic nuclear medicine is 0.03 mSv.

For most practical purposes, this quantity may be considered the same as the effective dose.

In those situations, the collective dose is still a useful quantity, provided it is made clear that the collective dose is that committed by the relevant source or unit of practice.

The Committee also uses the collective effective dose, which is the average dose to an exposed population or group multiplied by the number of people in the group.

The total collective effective dose in Europe, including the United Kingdom, was about 2,000 man Sv.

The annual effective dose per caput is still only about 10 per cent of that attributable to the diagnostic use of X rays. For countries of level I, the annual effective dose per caput is about 0.09 mSv.

However, neither the dose commitment to date nor the collective dose committed to date provides an adequate representation of the doses from practices that are likely to be continued into the future.

The local and regional collective effective dose from the whole test series was about 700 man Sv.

If the probability of late effects is proportional to effective dose at low doses, which is probably the case, the collective effective dose is an indicator of the total attributable harm to be expected in that group and its descendants.

The equivalent dose in each tissue or organ is multiplied by a tissue weighting factor, and the sum of these products over the whole body is called the effective dose.

The typical annual effective dose of 2.4 mSv from natural sources results in an annual collective dose to the world population of 5.3 billion people of about 13 million man Sv.

Since both the radiation weighting factor and the tissue weighting factor are dimensionless quantities, the dimensions of the equivalent dose and the effective dose are the same as the dimensions of the absorbed dose, and the unit is the same, the joule per kilogram.

The Committee has partially avoided that difficulty by using the dose commitment, which takes account of future doses committed by the source.

Tissue failures are therefore dependent on both dose and dose rate.

Uganda is committed to making the OAU Mechanism effective and usable.
