Handbook of Radiological Protection

Please find here a wealth of Health Physics data from the classic UK publication 'Handbook of Radiological Protection'. This information is provided under the PSI licence C2006010311 obtained from HMSO. The publication from 1971 is presented here for historical interest so use with great care. That said, much of the data present is equally valid today as it was decades ago.

It is true that more recent publications are probably more accurate, but this should not detract from the value provided by this resource.
