The case also provoked drastic changes in both the fields of workplace safety & liability, and the field of Health Physics, dealing with the health effects and safety issues involved in working with radioactive materials. In the late 1800s, the discovery of x-rays by Wilhelm Roentgen, radioactivity by Henri Becquerel, and radium by Pierre and Marie Curie birthed the study of radiation effects on living things . Among the findings was that there does not appear to have been an increase of birth defects in those that survived the blasts. Von Kirchhoff bis Planck.

His theory, and Joseph-Louis Lagrange's improvement on the calculation (applying the variational principle), do not take into account relativistic effects, which were unknown at that time. As early as 1897, it was concluded that x-rays could be used for therapeutic as well as diagnostic purposes, and in 1912, Marie Curie published the "Theory of Radioactivity." ;�mM���+�|��-7JӴ��m,��"?4���Ɯ�(�1(�r��kK{� ׫�Z�'ic�� ���5'�:�ɧ>�q�r3�p{�|�����U�Z(��88= % .h�% ��4��M��J G�p4X.H .j0isJù&i ��4]7�N���R4]��s�J��WcZ�������&� ��`�a��C�s�ڱ��(4�%!�`��Z�m��Pc����t:冗���r��\��G��W�'����Xizf�`g�Im$V(�[p�?Z楍��H�a�b�=��Tf�����(���(��� Z�_]�0���� ����s�֔�ʮƕ݌J*�a������呱�C��mq�ž�4�Ц_k �����WK�r�>�Z+BD��N $�S��F�1;���GP��:+C\}-o"M.EpS/�� {r{�}(˙] �;%-%P��))�QEmj͢X5�����$C��>����z�MF�(�ť��M�4�GM�loz���W. /R7 7 0 R Electromagnetic Radiation: History, Theory and Research $ 130.00.
