Managing the pregnant radiation worker: a realistic policy for hospitals today.

Effective, fair management of pregnant employees exposed to radiation requires the balancing of three factions: the rights of the expectant mother to pursue her career without discrimination based on sex; the protection of the the fetus, and the needs of the employer. Each hospital should establish a realistic policy which addresses these three concerns, by clearly articulating the expectations of the employer and the options available to the employee. Successful implementation of the policy depends on the means by which this information is communicated to all female employees exposed to radiation, so that they have a fair opportunity to exercise their options within the hospital's general employment policies.

Interpenetrating polymer networks for biological applications.

The use of a sequential polymerization method for preparing interpenetrating polymer networks with biocomatible surfaces has been studied. A hydrogel monomer was made to undergo polymerization with simultaneous cross-link formation, in the presence of a swollen thermoplastic elastomer heterophase block copolymer. On removal of the swelling solvent, an interpenetrating network of the hydrogel and the thermoplastic elastomer was obtained, which absorbed water in the manner of a hydrogel, but had mechanical properties superior to hydrogels. The studies employed a poly(ether-urethane) block copolymer as the thermoplastic elastomer. The materials fabricated included samples in which the interpenetrating polymerization extended throughout the termoplastic elastomer as well as samples in which the interpenetrating polymerization was confined to a region near the surface of the latter.
