Revised legislation carried on this site may not be fully up to date.

Please see ‘Frequently Asked Questions’ for details regarding the timescales for which new effects are identified and recorded on this site.
1.—(1) It can be assumed for the purpose of the determination of the wholesomeness of foodstuffs treated with an overall average dose of 10kGy or less that all radiation chemical effects in that particular dose range are proportional to that dose.
(2) The overall average dose,
, is defined by the following integral over the total volume of the goods:
where
M = the total mass of the treated sample
p = The local density at the point (x,y,z)
d = the local absorbed dose at the point (x,y,z)
dV = dx dy dz, the infinitesimal volume element which in real cases is represented by the volume fractions.
(3) The overall average absorbed dose can be determined directly for homogeneous products or for bulk goods of homogeneous apparent density by distributing an adequate number of dosimeters strategically and at random throughout the volume of the goods. From the dose distribution determined in this manner an average can be calculated which is the overall average absorbed dose.
(4) If the shape of the dose distribution curve throughout the product is well determined, the positions of minimum and maximum dose are known. Measurements of the distribution of dose in these two positions in a series of samples of the product can be used to give an estimate of the overall average dose.
(5) In some cases, the mean value of the average values of the minimum dose (
min) and maximum dose (
max) will be a good estimate of the overall average dose: i.e., in these cases:

This timeline shows the different points in time where a change occurred. The dates will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force. The first date in the timeline will usually be the earliest date when the provision came into force. In some cases the first date is 01/02/1991 (or for Northern Ireland legislation 01/01/2006). This date is our basedate. No versions before this date are available. For further information see the Editorial Practice Guide and Glossary under Help.
