Radiation Safety (Including Brachytherapy) - NCLEX-RN

Cluster care to minimize time near the source. Grouping tasks reduces cumulative time spent near the radiation source, adhering to the time principle of radiation protection to limit exposure.

Intensity is inversely proportional to $d^2$. This law explains that radiation intensity decreases with the square of the distance from the source, guiding safe positioning to reduce exposure.

Time, distance, and shielding. These principles minimize exposure by limiting duration, maximizing separation, and using barriers to reduce radiation dose according to ALARA guidelines.

Use lukewarm water and mild soap; pat dry. Gentle cleansing prevents further irritation to radiosensitive skin, promoting healing and reducing infection risk in the treated area.

Do not remove markings; avoid scrubbing the area. Markings ensure precise targeting of radiation beams, so preserving them maintains treatment accuracy and efficacy.

Lotions, powders, deodorants, or perfumes on the field. These products can interfere with radiation delivery or exacerbate skin reactions, so avoidance ensures safe and effective therapy.

Loose, soft clothing to reduce friction and irritation. Soft, loose fabrics minimize mechanical irritation to sensitive irradiated skin, aiding comfort and preventing exacerbation of dermatitis.

Protect from sun exposure; cover the area and avoid tanning. Irradiated skin is highly susceptible to UV damage, so protection prevents burns and long-term complications like hyperpigmentation.

Soft, bland foods; avoid spicy, acidic, and rough foods. Bland foods reduce irritation to inflamed mucosal tissues, alleviating pain and supporting nutrition during radiation-induced inflammation.

Fatigue. Radiation affects bone marrow and cellular energy, leading to systemic tiredness that requires energy conservation strategies.

Implement radiation precautions and restrict visitors as ordered. Sealed implants emit radiation, so precautions and restrictions protect staff, visitors, and the environment from unnecessary exposure.

No pregnant visitors or young children. Fetuses and children are more radiosensitive, so restrictions minimize risks of developmental harm or increased cancer susceptibility.

Use long-handled forceps to place it in a lead container. Forceps ensure safe handling without direct contact, and lead containers shield radiation, preventing exposure during retrieval.

Wear gloves; avoid direct hand contact with the source. Gloves protect against contamination, but avoiding hand contact minimizes direct radiation exposure from the sealed source.

Notify the radiation safety officer and the provider immediately. Immediate notification ensures expert assessment, proper disposal, and monitoring to mitigate risks from the dislodged radioactive source.

Maintain prescribed bedrest; avoid dislodging the implant. Bedrest prevents movement that could shift the implant, ensuring targeted radiation delivery and reducing complication risks.

Use stool softeners and manage urinary catheter as ordered. These measures prevent straining or pressure that could dislodge the implant, maintaining treatment integrity and patient safety.

Radiation precaution signage per facility policy. Signage alerts personnel and visitors to radiation hazards, ensuring adherence to safety protocols and minimizing unintended exposure.

Personal dosimeter badge. Dosimeters track cumulative radiation dose, enabling monitoring and ensuring staff exposure remains within safe regulatory limits.

Avoid assigning pregnant staff to care for the patient. Pregnant staff are at higher risk due to fetal radiosensitivity, so reassignment protects both the employee and the developing fetus.

Maintain the greatest feasible distance from the source. Increasing distance from the brachytherapy implant follows the inverse square law, significantly reducing radiation intensity and exposure risk.

Stop exposure and report to radiation safety/employee health. Prompt reporting allows for medical evaluation, dosimetry review, and implementation of protective measures to address potential health risks.

Skin integrity in the radiation field. Radiation can cause dermatitis, so monitoring skin for erythema, dryness, or breakdown allows early intervention to prevent complications.

Lead shielding (for example, lead apron/portable lead barrier). Lead effectively attenuates gamma radiation emitted from brachytherapy sources, providing essential protection during patient care.
