that is a reasonable indicator, for which the food or raw material

treated with radiation, referred to in annex 1.

Packaging and method of labelling of foods and raw materials irradiated by ionizing


(1) the materials used for packaging foods and raw materials intended for the treatment of

ionizing radiation must comply with the requirements laid down in a special

legislation. ^ 6)

(2) Food and raw materials treated with ionising radiation, including the irradiated

intended for the final consumer and the Joint Board, must be

marked in accordance with the law.

(3) food and ingredients treated with ionising radiation, which are not

intended for the final consumer and the Joint Board, must be

marked ' treated with ionising radiation "or" treated with ionizing "

even in the case of food or raw material, which is a component of the food and

the raw materials that are not treated with ionising radiation. This information is

shall appear on the packaging next to the folder name of the food. At the same time on the packaging shall indicate the

name and address of the facility performing the treatment or its reference number

allocated upon approval of its operation.

(4) treatment of foods and ingredients with ionising radiation must be marked

in all the documents accompanying an irradiated food or with her


Final provisions

For the purposes of the assessment of the wholesomeness of irradiated foods and raw materials

the overall average dose of 10 kGy or less you can assume that

all radiation chemical effects in that particular dose range

are proportional to the dose.

Overall average absorbed dose is defined by the following

by the following integral over the entire volume of the product:


D =-integral p (x, y, z) d (x, y, z) dV

M (in)

When M = total weight of the treated product [kg]

p = local density at a point (x, y, z) [kg.m-3]

d = local dose absorbed in the time of (x, y, z) [J.kg-1]

DV = dy dy dz elementary volume in real cases

represented by volumes of factions

For homogeneous products or unwrapped products seemingly homogeneous

the density can be determined overall average absorbed dose directly so

that insert a sufficient number of dosimeters strategically or randomly

the mass of the products. From the thus provided for batch distribution calculates the average,

that represents the overall average absorbed dose.

If the distribution of benefits within the curve of the product precisely, we obtain

the location of the minimum and maximum doses. Distribution of benefits in these two

positions can be measured in a series of samples of the product in order to obtain

the overall average dose.

Overall average dose is calculated as the average of the values of the minimum dose

(Dmin) and maximum (Dmax):

Dmax + Dmin

the overall average dose =-----------



The ratio of----< 3



and regular implementation of irradiation), prior to certain categories of foods in the

irradiation unit sets out the position of the points, the minimum and maximum

doses and dose measurements are carried out on the total weight of the products. This

validation measurements must be carried out in sufficient numbers (at least

three times) in order to take account of the variations in density, or geometric

the parameters of the products.

(b)) the measurement must be repeated when there is a change of the product,

geometrical parameters or conditions of irradiation.

c) routine measurements are performed during the irradiation, in order to ensure that the

the limit values are not exceeded. To perform these measurements shall be

dosimeters are able to measure the minimum or maximum level of benefits or

reference level. The reference position must be secured in an appropriate

place outside or inside the product, just a slight fluctuation of the

e) if liquid bulk products, casting, location of points the minimum and

maximum benefits are not. In this case, you must use the

dosimetric probe to determine the value of the highest doses. The measurement is

only measuring instruments with the approved type and a valid verification

the correct position of the source. The radiation particle accelerator is checked and

registers the speed of traffic product, level of energy, a flow of electrons,
