Many factors complicate the study of the dose effect relationship.

For sparsely ionizing radiations, such as X rays, the net effect of these processes is such that the dose effect relationship for most stochastic effects is curvilinear.

As the dose increases, more individuals will incur the observable effect, up to a dose above which the whole group shows the effect.

Because the proportion of cells killed depends on dose, the severity of the deterministic effect also depends on dose.

Many animal experiments confirm the predicted shape of the dose response relationship.

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

If the exposures are limited to a range in which the dose response relationship is approximately linear, the quantities can also be expressed per unit dose.

The probability of this occurring is related to dose by the same type of dose relationship (linear or linear quadratic) as discussed for heritable mutations in the cell.

Others even went further for a double dose of care in defiance to the relationship between camels and the coronavirus.

This type of effect is called deterministic, because it is sure to occur if the dose is large enough.

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

And sure enough, we found a dose response relationship, just like we found in the arterial blockages in our cardiac studies.

With densely ionizing radiation, for example, alpha particles, there are fewer, but denser, tracks per unit dose, and each track is more likely to produce damage that is not successfully repaired, so the relationship is more likely to be proportional to dose at all doses and dose rates.

The dose referred to is almost always the effective dose.

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

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

What's the dose?

The theoretical and experimental results are thus combined to obtain a quantitative relationship between dose and the probability of occurrence of the relevant cancer.

Cell killing by radiation can be quantitatively studied in cell cultures in vitro to gain information on the shape of the dose response relationship.

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

One important effect of exposure to radiation in utero is a dose related increase in mental impairment, up to and including severe mental retardation.

By omitting the context, the report failed to present the relevant relationship between cause and effect.

Give me a dose

In the UNSCEAR 1988 report, the Committee derived risk coefficients (risk per unit dose) for high dose and high dose rate situations for various tissues.

It wasn't a big dose?

While individual cell killing is a stochastic effect, organ and tissue failures require the killing of large numbers of cells and therefore have thresholds of dose.

Collective effective dose (million man Sv)

So milliliters of solution per dose.

A dose is every twelve hours.

Better give him a good dose.

I'll give you the right dose.

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

Again, not an insane dose, not an illegal dose, but very much at the high end of normal.

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

Nigerians can use a dose of hope.

We're still getting a dose of UVA.

And I had this idea what if I could, in effect, virtually embed, and create a permeable relationship with the soldiers?

The average dose from external exposure was estimated to be 0.12 Sv, giving a collective dose of about 30,000 man Sv.

Stochastic health effects occur by chance, generally occurring without a threshold level of dose, whose probability is proportional to the dose and whose severity is independent of the dose, such as cancer and genetic effects.

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).
