A16-1 Population and land use

The exclusion criteria adopted are the following:

1. A population factor weighted over circular rings lower than 20 000 with a weight given by Table A16-1 (or by an equivalent bi-logarithmic graph).

   Table A16-1: Population factor

   Distance (km)	Factor
   1	1
   2	0.66
   5	0.25
   10	0.07
   15	0.03
   20	0.001

2. A population factor weighted on the most unfavourable 22 30 ? sector from the origin up to 50 km, lower than 6500 (with the weight given by r ^?1.5, where r is the distance in kilometres.

3. A distance of at least 10 km from population centres with many hundreds of thousands of inhabitants.

4. A distance of at least 20 km from population centres with many hundreds of thousands of inhabitants.

5. The availability, around the centre of the site, of a circular area of the diameter of about 1 km which can be put under the direct control of the utility.

The criteria on the population distribution and on its weight are connected with the assumption of an accidental release of 3.7 10 ¹³ Bq of iodine-131 and of the other associated nuclides, with a maximum effective dose to the individual (adult) equal to 0.01 Sv and with a thyroid maximum dose of a few tens of millisieverts.

The criteria concerning population centres are connected with the possibility to proceed, in case of very serious accident, to the evacuation of population centres.
